Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a combined visual grasping forceps. Background Art

[0002] Currently, urological surgery is usually used for treatment. After urological surgery, a ureteral stent needs to be placed to ensure smooth drainage, and at the same time, it promotes wound recovery and prevents stenosis. Eventually, it needs to be removed. The current common surgical method is to enter the bladder through the urethra with a cystoscope. The foreign body forceps pass through the instrument channel of the cystoscope, and under the guidance of observing the cystoscope image, the ureteral stent retained in the bladder is grasped and withdrawn from the body together with the cystoscope.

[0003] Generally, due to the limitation of its optical structure, the cystoscope has a relatively thick and rigid mirror tube diameter, which causes great pain and trauma to the patient when entering the human body. When using the cystoscope, it needs to be connected to a camera host and a display, and the operation is relatively cumbersome and not convenient for transportation. In addition, since the cystoscope must be repeatedly cleaned and disinfected for use, it increases the surgical cost and the risk of cross-infection caused by incomplete disinfection. For this reason, we propose a combined visual grasping forceps. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a combined visual grasping forceps, which can ensure that the maximum outer diameter of the insertion part entering the human body is thinner and semi-rigid compared with the outer diameter of the cystoscope, can effectively reduce the pain and injury of the patient, the transparent head end of the grasping forceps isolates the endoscope from the human body, isolates bacteria from contacting the endoscope, the endoscope does not need to be cleaned and disinfected, and the grasping forceps are disposable. Due to its simple structure and high molecular material, the overall cost is low, and the surgical cost is effectively reduced.

[0005] To solve the above technical problems, the utility model adopts the following technical measures:

[0006] A combined visual grasping forceps includes a grasping forceps and a hand-held endoscope. The grasping forceps includes a connecting head, a forceps head control handle, a main body outer tube and a forceps head.

One end of the white balance button 251 and the brightness adjustment button 252 penetrates through the handheld handle 25 and is located outside the handheld handle 25. The battery 253 and the charging interface 27 are integrally arranged, and the charging interface 27 is arranged at the bottom end of the handheld handle 25; the display screen 22 is arranged on the back of the housing 21, and the image processing circuit board 211 is arranged inside the housing 21.

[0024] Currently, urological surgery is usually used for treatment. After urological surgery, a ureteral stent needs to be placed to ensure smooth drainage, and at the same time, it promotes wound recovery and prevents stenosis. Eventually, it all needs to be removed. The current common surgical method is that the cystoscope enters the bladder through the urethra, and the foreign body forceps pass through the cystoscope instrument channel. Under the guidance of observing the cystoscope image, the ureteral stent left in the bladder is grasped and withdrawn from the body together with the cystoscope.

[0025] Generally, due to the limitations of its optical structure, the cystoscope has a relatively thick and rigid tube diameter, which causes great pain and trauma to the patient when inserted into the human body. When using a cystoscope, it needs to be connected to a camera host and a display, with cumbersome operation and inconvenient transportation. In addition, since the cystoscope must be repeatedly cleaned and disinfected for use, it increases the surgical cost and the risk of cross-infection caused by incomplete disinfection.

[0026] 1. The light guide optical fibers arranged at the front end of the endoscope body conduct the light emitted by the built-in LED lamp module (the front LED lamp emits light through the image processing circuit board) to the front end to illuminate the human tissue. The optical signals collected by the electronic imaging module arranged at the front end are transmitted to the image processing circuit board through wires and displayed on the display screen. The electric field module in the hand-held handle supplies power to the circuit board and the display screen.

[0027] 2. The grasping forceps are provided with an image channel to guide the endoscope into the transparent head end at the front end. The transparent head end has a transparent thin wall corresponding to the cross-section of the image channel. The endoscope can illuminate and observe the interior of the human body through this transparent thin wall and isolate the endoscope from the human body. The water injection channel is communicated with the grasping forceps channel. The injected water flows through the gap between the forceps channel and the grasping forceps to the front end to wash the image field of view of the endoscope. The rotation and movement control handle channel of the forceps head is held by hand to perform rotation and movement actions to move the front forceps head back and forth. The forceps head rotates, and the opening and closing control handle of the forceps head moves by fingers to open and close the front forceps head.

[0028] 3. The hand-held endoscope and the grasping forceps are combined together. Press the power on / off button to start the endoscope, adjust to the appropriate brightness through the light brightness adjustment button, correct the image color through the white balance button, retract the forceps channel into the outer tube of the main body through the rotation and movement control handle of the forceps head. Under image monitoring, the outer tube of the main body enters the bladder through the urethra. After observing the ureteral stent, move the forceps head to the ureteral stent through the rotation and movement control handle of the forceps head, rotate the forceps head to the appropriate clamping direction, and clamp the ureteral stent and take it out of the body together with the grasping forceps;

[0029] It can ensure that the maximum outer diameter of the insertion part entering the human body is slender and semi-rigid compared with the outer diameter of the cystoscope, effectively reducing the pain and injury of the patient. The transparent head end of the grasping forceps isolates the endoscope from the human body, preventing bacteria from contacting the endoscope. The endoscope does not need to be cleaned and disinfected, and the grasping forceps are for single use. Due to its simple structure and high molecular material, the overall cost is low, effectively reducing the surgical cost.

[0030] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the purpose of the present invention.
