How to choose the right laparoscopic surgical instruments?

Choosing the right laparoscopic surgical instruments requires comprehensive consideration of multiple factors, including the type of surgery, viewing angle requirements, instrument functions and safety, etc. The following are detailed selection criteria:

Type and site of surgery:

Colorectal cancer surgery: The commonly used laparoscopic lens is a 30° lens because it is the most widely used in colorectal tumor surgery.

Gynecological surgery: The 0° lens is more suitable because it provides the best direct vision effect.
Viewing angle requirements:

0° lens: Provides clear direct vision and is suitable for surgeries that require precise operations, such as gynecological surgery.

30° lens: Provides a surgical field of view at a special angle and is suitable for surgeries that require observation of specific structures, such as lymph node removal.
Instrument function and safety:

Conventional surgical instruments: including pneumoperitoneum needles, cannula puncture needles, separation forceps, non-destructive grasping forceps, scissors, needle holders, Hem-o-lok clip appliers, specimen bags, purse-string forceps, incision protectors, etc.
Energy instruments: such as ultrasonic scalpels, radiofrequency hemostatic scalpels, microwave scalpels, etc., are used for high-frequency surgery and can meet the needs of various surgical scenarios.
Anti-adhesion coating: The material of the forceps head is specially treated to effectively reduce tissue adhesion and improve surgical efficiency.
Technical parameters:

Working length: For example, the working length of some instruments is 330mm.
Electromagnetic compatibility: Select cables and surgical instruments that meet relevant standards to ensure electromagnetic compatibility.
Disposable instruments:

Disposable laparoscopic high-frequency surgical instruments can meet the needs of various surgical scenarios and reduce the risk of cross-infection.
Communication and experience sharing:

You can communicate with the purchasing departments of other hospitals to understand their selection criteria and lessons learned in order to make better decisions.
The selection of appropriate laparoscopic surgical instruments requires comprehensive consideration of multiple factors such as the type of surgery, viewing angle requirements, instrument function and safety. By referring to expert consensus and technical guidelines, you can more scientifically select suitable surgical instruments, thereby improving the quality and safety of surgery.

What are the specific applications and advantages of 30° lenses in colorectal cancer surgery?

In colorectal cancer surgery, the specific application and advantages of the 30° lens are mainly reflected in the following aspects:

Multi-angle field of view: The 30° lens can provide multi-angle surgical images by rotating the optical fiber, which enables the surgeon to better observe the "corners" such as the side of the pelvis and the back of the uterus. This multi-angle field of view is particularly important for colorectal cancer surgery because these parts are often difficult to see directly.

Broad field of view: The visual range of the 30° lens is a cone space, and this structure can greatly increase the visual range of the operation. This is a huge advantage for surgeons because it can help them explore the lesion area more comprehensively, thereby improving the accuracy and safety of the operation.

Suitable for complex surgery: In colorectal cancer surgery, especially radical resection of rectal cancer, the multi-angle field of view of the 30° lens helps to better dissect the fascia and protect the autonomic nerves. The flexibility and wide field of view of this lens make the operation smoother.

Compared with traditional 2D laparoscopes: Although some 3D laparoscopes have 0° lenses and their field of view is narrower than that of 30° lenses, 30° lenses still have their unique advantages. When cleaning the root of the inferior mesenteric artery, the angle can be slightly adjusted to achieve the 30° visual effect of ordinary 2D laparoscopes, which is particularly convenient for rectal cancer surgery.

Improve surgical results: Since the 30° lens can provide a wider field of view and multi-angle observation, the surgeon can more easily identify and handle complex surgical situations, thereby improving the success rate of surgery and the quality of life of patients.

The application of 30° lenses in colorectal cancer surgery has significant advantages, including providing a wide field of view from multiple angles, being suitable for complex surgeries, and improving surgical results.

What are the best use scenarios and effect evaluations of 0° lenses in gynecological surgery?

The best use scenarios and effect evaluations of 0° front-view lenses in gynecological surgery are as follows:

Best use scenarios
The 0° front-view lens cannot be observed from multiple angles due to its narrow field of view, and can only look forward, so it is mainly used in simple single-port laparoscopic (LESS) surgery. This lens is suitable for operations that do not require a wide field of view, such as single-port laparoscopic exploration and some basic surgical operations.

Effect evaluation
The application of 0° front-view lens in gynecological surgery has certain limitations. Due to its narrow field of view, it may increase the difficulty of the operation and limit the scope of the surgical field of view. However, for some simple surgical tasks, such as uterine myomectomy and total hysterectomy, the 0° front-view lens can still provide sufficient support.

The 0° front-view lens is mainly used for simple surgical operations in gynecological single-port laparoscopic surgery. Its field of view limitation makes it more suitable for scenes that do not require a wide field of view.
