Problems solved by technology

Before the operation, several bags of normal saline are usually suspended in advance. During the operation, the normal saline may also need to be replenished. If the normal saline is not replenished in time, the bladder will shrink and return to its natural normal state due to the lack of normal saline. It will be very small. If the cutting edge of the planing system is used to crush the tissue at this time, there is a great possibility that it will touch the inner wall of the bladder and accidentally injure the bladder, which has a great risk of surgery

Embodiment 1

[0042] This embodiment provides an underwater planing system capable of avoiding bladder damage, which includes an endoscope system, a planing main body system and a liquid pressure sensor system.

[0043] Specifically, see Figure 3 to Figure 6 , the endoscopic system is a bladder endoscope 10, including a handle 11 and an outer sheath 12 connected to each other, and the handle 11 is provided with a surgical instrument interface, a camera system interface, a light source interface and two liquid pressure sensor interfaces 111 The outer sheath 12 is provided with a working channel 121 , an imaging channel 126 , a light guide channel 125 and a liquid pressure sensing channel 122 all extending along the length of the outer sheath 12 . The surgical instrument interface communicates with the working channel 121, the camera channel 126 communicates with the camera system interface, the light guiding channel 125 communicates with the light source interface, and the liquid pressure s...

Embodiment 2

[0055] This embodiment provides another underwater planing system that can avoid bladder damage. It is similar to the idea and principle of Embodiment 1, the only difference is that the type of the liquid pressure sensor and the specific sensing principle are different. Correspondingly, the liquid pressure sensor The structure of the system is different, and the connection structure of the control part in the liquid pressure sensor system and the planing main system is also different.

[0056] Such as Figure 11 As shown, the liquid pressure sensor of this embodiment is a pressure transmitter module, which includes a hollow pipe 200, a pressure sensor 300 and a signal receiving end 400, and the head end of the hollow pipe 200 extends into the planer head 100 together. To the bladder, the tail end is connected to the pressure sensor 300 , the pressure sensor 300 is connected to the signal receiving end 400 , the signal receiving end 400 is connected to the control device, speci...

Embodiment 3

[0062] This embodiment provides another underwater planing system that can avoid bladder damage, which is similar to the idea and principle of Embodiment 2, the only difference is that: Figure 12 As shown, the pressure sensor is arranged inside the host 610, and the hollow tube 220 includes a first hollow tube 221 and a second hollow tube 222. The first hollow tube 221 is set outside the host 610, and its head end is used to extend into the bladder. The way of carrying the bladder endoscope into the bladder is the same as the way of carrying the bladder endoscope into the bladder in the first embodiment. The second hollow pipe 222 is set in the host 610, and the first The tail end of the hollow pipe 221 is installed on the main machine 610 through a waterproof sealed threaded quick connector, and is in sealing communication with the second hollow pipe 222, and the second hollow pipe 222 is connected to the pressure sensor provided inside the main machine 610 through the cable ...

Abstract

The invention provides an underwater shaving system capable of avoiding bladder damage and a use method. The system comprises a shaving main body system and a liquid pressure sensor system, wherein the shaving main body system comprises a shaving cutter head and a control device for controlling the shaving cutter head to work; the liquid pressure sensor system is in signal connection with the control device and is used for sensing liquid pressure information in a bladder, and when the liquid pressure information is lower than a preset threshold, the control device controls the shaving cutter head to stop shaving and cutting actions. According to the underwater shaving system, the occurrence probability of an accident that the bladder is accidentally injured during prostatectomy can be greatly reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel underwater planing system and a usage method that can avoid bladder damage. Background technique [0002] The power planing system for soft tissue surgery is a soft tissue pulverization and suction device used in underwater surgery. It is mainly used in transurethral prostatectomy (enucleation) and gynecological soft tissue resection. The device cooperates with underwater enucleation of the prostate to quickly remove large pieces of tissue placed in the bladder after enucleation and stripping, and sucks the pulverized tissue out of the body through a self-contained negative pressure pump into a negative pressure liquid collection bottle. [0003] When the enucleated tissue is pulverized in the bladder, the bladder needs to be filled with normal saline. After the bladder is filled with normal saline, it expands rapidly, and its volume will become much larger than that in t...
