Description

Multi-channel working sleeve

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multi-channel working sleeve.

Background

The concept of "minimally invasive" has been advanced into various fields of surgery due to its superiority of minimally invasive surgery, low pain, and fast recovery. The minimally invasive surgery is a surgery which is performed by modern medical instruments such as a laparoscope, a thoracoscope and the like through a multi-channel working cannula and related equipment.

The current multichannel work sleeve pipe is stretching into human during operation, because the rupture of internal blood vessel of human body makes blood flow out, can lead to the field of vision fuzzy when inserting the endoscope in multichannel work sleeve pipe and observing, influences the observation, and then sets up the clean realization that water injection channel can keep the endoscope mirror surface through the water injection and observe clearly in the sleeve pipe.

However, when water is injected into a human body, the injected water often overflows from the multi-channel working sleeve and flows onto the hands and the ground of an operator, so that the operation of a doctor is influenced and the ground is wetted, and inconvenience is brought.

Therefore, in view of the current situation that the conventional multi-channel working casing does not implement a special drainage measure, it is an urgent problem to develop a multi-channel working casing having a drainage channel to achieve timely drainage.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the invention provides the multi-channel working sleeve with the drainage channel to realize timely drainage, so as to solve the problem that the injected water often overflows from the multi-channel working sleeve when the existing multi-channel working sleeve is not provided with a special drainage measure.

The technical scheme adopted by the invention for solving the technical problems is as follows: a multi-channel working sleeve comprises a sleeve body, wherein a drainage channel is arranged on the sleeve body, and a drainage port communicated with the drainage channel is formed in the sleeve body. Through set up drainage channel on multichannel work sleeve pipe, water can be discharged through water injection channel when can realizing using the sleeve pipe to the internal water injection of human to discharge special water-collecting device, avoid influencing doctor's operation and wet ground.

Furthermore, the sleeve body comprises a main channel pipe, an auxiliary channel pipe and a cushion block, the main channel pipe and the auxiliary channel pipe are integrally arranged, the cushion block is positioned between the main channel pipe and the auxiliary channel pipe, the drainage channel is composed of the main channel pipe and the auxiliary channel pipe, the main channel pipe and the auxiliary channel pipe are communicated at the rear part of the cushion block, and the drainage port is communicated with the main channel pipe and the auxiliary channel pipe. The main channel pipe and the auxiliary channel pipe are used for draining water, so that the structure is simplified, and the realization is easy.

Further, the water outlet is arranged on the rear end pipe wall of the main channel pipe and/or the secondary channel pipe. The water outlet is arranged at the rear end, so that the distance between the water outlet and the front end of the sleeve body is greater than the depth of the sleeve body entering a human body, the sleeve entering the human body is not influenced, and the water can be discharged when the water level reaches a certain height.

Furthermore, a water discharge nozzle is connected to the water discharge port.

Furthermore, the rear part of the cushion block is provided with a notch which enables the main channel pipe and the auxiliary channel pipe to be communicated, and the notch divides the cushion block into a lower cushion block and an upper partition wall.

Furthermore, a water injection channel is arranged in the cushion block, a water outlet of the water injection channel is positioned at the front end of the lower cushion block, a water inlet of the water injection channel is positioned in the upper partition wall, and a water injection port is formed in the upper partition wall. And water is injected into the water injection channel through the water injection port.

Further, the water injection channel is provided with two. When the amount of bleeding is big, need increase the water injection volume, can wash totally fast like this, in addition, increase water injection speed, can increase the pressure around the water filling port, the prevention that can be better is bled, and this pressure is to balance the internal blood vessel of human body, prevents or reduces and bleeds.

Furthermore, a water injection nozzle is connected to the water injection nozzle.

Furthermore, the casing body further comprises a handle arranged at the rear ends of the main channel pipe and the auxiliary channel pipe, and the handle is provided with a main channel pipe orifice communicated with the main channel pipe and an auxiliary channel pipe orifice communicated with the auxiliary channel pipe.

According to the technical scheme, the invention has the following advantages:

through set up drainage channel on multichannel work sleeve pipe, water can be discharged through water injection channel when can realizing using the sleeve pipe to the internal water injection of human to discharge special water-collecting device, avoid influencing doctor's operation and wet ground. The water injection pressure is reduced by arranging two water injection channels.
