Description

Technical Field

[0001] The utility model relates to the technical field of laparoscope cleaning, in particular to a laparoscope sleeve assembly which can be used to clean a laparoscope lens during surgery. Background Art

[0002] A laparoscope is a minimally invasive surgical instrument. Laparoscopic surgery uses a trocar to make a hole in the patient's abdomen. The laparoscope enters the patient's body through the trocar to work. An optical lens assembly is built into the lens end of the laparoscope to transmit illumination light and images of the abdominal cavity. The other end is connected to a camera device. When the laparoscope enters the patient's body, the optical assembly inside the laparoscope provides a light source channel for the surgical field of view. The optical lens assembly built into the laparoscope can transmit the image of the abdominal cavity to the camera device, allowing the surgeon to clearly see the image of the patient's abdominal cavity on the screen of the camera device. Currently, laparoscopes are widely used in laparoscopic minimally invasive surgeries. Therefore, minimally invasive surgeries in gynecology, gastrointestinal surgery, hepatobiliary surgery, and urology require the assistance of laparoscopes.

[0003] During laparoscopic surgery, contamination of the laparoscope lens, such as fogging, blood splattering, etc., will affect the surgical field of view. Contamination may cause the lens to blur, affecting the doctor's clear observation of the surgical site and reducing the accuracy and effectiveness of the surgery. During surgery, the laparoscope lens often needs to be pulled out of the abdominal cavity for cleaning or replacement, which will inevitably lead to loss of surgical field of view, thereby prolonging the operation time. Moreover, each time the laparoscope is used and contaminated, it needs to be disinfected, and the utilization rate of laparoscopes is low. Therefore, contamination in laparoscopic surgery is a problem that needs to be solved. There are currently many solutions to solve laparoscope contamination, but they are difficult to apply in practice. In addition, many of them have changed the original structure of the laparoscope, making the structure complex, which makes promotion difficult and costly. Utility Model Content

[0033] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-12As shown, the present invention provides a laparoscope cannula assembly that can be used to clean the laparoscope lens during surgery, including a laparoscope body 1 and a cannula 2. The laparoscope body 1 and the cannula 2 are nested and matched. The inner wall of the cannula 2 is provided with a water spray channel 3 along its length, which can spray water or air toward the laparoscope lens. During use, the laparoscope is inserted through a laparoscope puncture device into the patient's abdominal cavity. When the laparoscope lens is contaminated or fogged, the water spray or air jet channel can be used to spray water or air jet to clean the laparoscope lens, which can effectively clean the lens, avoid contamination of the laparoscope lens, improve the doctor's clarity of observation of the surgical site, and enhance surgical precision.

[0035] As a preferred embodiment of this case, the rear end of the cannula 2 is provided with a rubber ring that fits tightly with the laparoscope, which can achieve a seal between the cannula 2 and the laparoscope body 1 (i.e., the laparoscope shaft) to prevent gas leakage from the patient's body. A connector 4 is also provided, which is connected to the water spray channel 3. This connector 4 is preferably a Luer connector and can be connected to an air pump or water pump to deliver water or air through the water spray channel 3. An external heater is also provided to heat the water spray or air jet used for lens cleaning. A fastening device 6 is provided below the Luer connector, which is preferably a fastening bolt.

[0036] The sleeve 2 has two embodiments, one of which is Figure 10 As shown, the length of the sleeve 2 is shorter than that of the laparoscope body 1.

[0038] refer to Figure 12 As shown, the water spraying direction of the water spray hole 301 is opposite to the inclined surface direction of the laparoscope lens. In this way, the water spraying direction is perpendicular to the inclined surface direction of the lens, and the water can be dispersed when it contacts the lens, so as to rinse more fully.

[0039] Another embodiment, referring to Figure 12 The length of the sleeve 2 is greater than that of the laparoscope body 1, and the sleeve 2 is 3-5 mm longer than the length of the laparoscope body 1. The front end of the water spray channel 3 is an angled nozzle that can spray water or air toward the laparoscope lens.

[0040] Furthermore, a glass lens is installed near the front end of the water spray channel 3. The glass lens structure can complete the sealing of the laparoscope lens body, which can prevent the blood in the patient's body from directly contaminating the lens. When cleaning, you can directly clean the glass piece. Since the laparoscope lens is not contaminated, it can be used again in the next operation, thereby improving the utilization rate of the laparoscope.

[0041] In order to improve the strength of the sleeve 2, the cavity cross-section of the sleeve 2 is an eccentric circle, and a mounting groove 201 is opened along the length direction of the sleeve 2 at the position where the eccentric circle wall is thickest; the water spray channel 3 is connected to the mounting groove 201 by bonding or welding.
