Description

Cleaning device for laparoscope puncture outfit

Technical Field

The utility model belongs to the field of cleaning tools for medical operations, and particularly relates to a cleaning device for a laparoscopic puncture outfit.

Background

Minimally invasive surgery such as laparoscopic surgery gradually replaces open surgery with the development of surgical techniques, and is becoming more and more popular. During operation, an operation channel is established on the abdominal wall of a patient through the puncture outfit, and an operation instrument enters the abdominal cavity of the patient through the puncture outfit. However, after puncturing, the inner wall of the puncture cannula is often stained with blood, so that the lens is stained and blurred when the laparoscope enters and exits the cannula, and therefore, the puncture outfit needs to be cleaned.

The existing foreign puncture outfit wiping device is similar to a long cotton swab, but the foreign wiping device has high cost, and no corresponding device is marketed in China. At present, common cotton swabs or small gauze strips are often used for wiping in domestic clinical work. However, this approach has the following problems: (1) The common cotton swab is not long enough and cannot extend into the puncture outfit completely, namely the full length of the puncture outfit cannot be wiped, so that the puncture outfit cannot be cleaned thoroughly; (2) The thinner puncture outfit such as the 8mm puncture outfit used by the da vinci robot can not be wiped by using a gauze strip; (3) cotton often falls off and is blocked in the puncture outfit; (4) When the gauze stuck with blood is taken out from the puncture outfit, secondary pollution can be caused to the inner wall of the puncture outfit due to the extrusion of the outlet sealing device.

Disclosure of Invention

Aiming at the defects of the related art, the utility model aims to provide a cleaning device for a laparoscope puncture outfit, which aims to solve the problem that the puncture cannula cannot be thoroughly cleaned in the existing puncture outfit cleaning mode.

In order to achieve the above object, the present utility model provides a cleaning device for a laparoscopic puncture outfit, comprising: a grip portion and a wiping portion;

the wiping part is connected with the holding part;

the wiping part is in a conical surface shape. The design of the conical surface is convenient for the wiping part to enter the puncture outfit, and the sealing device of the outer opening of the puncture outfit is not easy to be damaged to cause air leakage.

Further, the wiping part comprises a main body part and an edge part positioned at the circumferential direction of the main body part;

the thickness of the main body portion is smaller than that of the edge portion. Such a design facilitates the inversion of the morphology when the wiping part 2 is taken out, while the thicker edge part 202 is beneficial to increasing the contact area between the wiping part 2 and the inner wall of the puncture outfit, and improving the cleaning efficiency.

Further, the wiper surface is coated with a hydrophobic coating. Through the design of conical surface cooperation hydrophobic coating for when wiping portion overturns, blood sewage or drop on it can shake off and can not be stained with on the wiping portion thereupon, avoided the puncture ware to take out secondary pollution sleeve pipe inner wall in-process.

Further, the wiping part is made of flexible biocompatible materials, so that the inner wall of the sleeve is prevented from being scratched, and toxic substances are not remained.

Further, the wiping part is fixedly connected with the holding part. The mode of fixed connection avoids the falling of the wiping part possibly caused by wiping in the operation, and improves the safety of the operation process. Unlike available cotton swab, the cotton cleaner has no cotton falling off.

Further, the grip portion includes a handle and a stem portion, the handle being located at one end of the stem portion.

Further, the handle is provided with an anti-slip pattern so that an operator can hold the device more stably.

Further, the handle is made of an anti-slip material, so that slipping is avoided during holding.

Further, the rod part is provided with a stop part, so that the handle is prevented from excessively extending into the abdominal cavity to damage the viscera, and the safety is improved.

Further, the stop portion is a blocking piece.

According to the technical scheme, unlike the traditional cotton swab or gauze strip cleaning mode, the cleaning part of the device is in a conical surface shape, can conveniently extend into puncture outfits with various calibers, and can clean the whole length of a puncture sleeve, so that the inside of the puncture outfit can be thoroughly cleaned; in addition, the design of conical surface cooperation hydrophobic coating for when wiping portion overturns, blood dirt or drop on it can shake off and can not be stained with on the wiping portion thereupon, avoided the puncture ware to take out the in-process secondary pollution sleeve pipe inner wall.
