Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tissue sampling tool for endoscopic surgery. Background Technology

[0002] Tissue sampling tools used in endoscopic surgery mainly include biopsy forceps, clamps, and tumor forceps. These tools are usually used in conjunction with the endoscope to collect tissue through the instrument's channels for pathological examination or other laboratory analysis. Biopsy forceps are finely designed instruments that allow for precise tissue sampling under endoscopic guidance. Clamps and tumor forceps are used to remove lesions such as tumors, polyps, and other abnormal tissues. In addition, there are some special types of sampling tools, such as disposable flexible biopsy forceps, which have good quality and accuracy and are crucial to the surgical outcome.

[0003] Tissue sampling is a common procedure in endoscopic surgery. Traditional sampling tools have problems such as high coefficient of friction, poor chemical stability and poor biocompatibility, which may cause unnecessary harm to patients or cause inflammatory reactions during the sampling process. In addition, existing sampling tools are also inadequate in terms of lighting and control, which affects the accuracy and convenience of the operation.

[0004] Therefore, we provide a tissue sampling tool for endoscopic surgery to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tissue sampling tool for endoscopic surgery, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tissue sampling tool for endoscopic surgery, comprising an electronic controller, a rotating shaft disk disposed on the outer side of the electronic controller, a sampling and wire drawing motor mounted on the lower side of the electronic controller, and a wire drawing button mounted on the outer side of the sampling and wire drawing motor.

[0007] Preferably, a signal connection line is provided on the upper side of the electronic controller, and an extension hose is adhered to the rear side of the electronic controller. The extension hose is made of polytetrafluoroethylene.

[0008] Preferably, the end of the extension hose is provided with a hollow wire groove, the inner side of the hollow wire groove is connected to a metal wire, the outer right end of the metal wire is provided with a wire tube, the end of the metal wire is connected to a clamping plate, the inner side of the clamping plate is provided with a sampling clamping head, and the metal wire and the sampling clamping head form a closed structure through a sampling wire drawing motor.

[0009] Preferably, a miniature rotary motor is welded to the middle of the hollow wire groove, a motor connection kit is welded to the end of the miniature rotary motor, a sampling connector is welded to the outside of the motor connection kit, and the rotating shaft disk and the miniature rotary motor form a rotation control structure through an electronic controller.

[0010] Preferably, an optical fiber lamp is installed on one side of the clamp, and a miniature camera is installed on the other side of the clamp.

[0011] Preferably, the miniature camera and the fiber optic lamp are symmetrically arranged via a clamp, and the miniature camera and the electronic controller are electrically connected via a signal connection line.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The extension tubing made of polytetrafluoroethylene (PTFE) has an extremely low coefficient of friction, which minimizes resistance when the catheter moves through the endoscope's working channel or inside the body. It also exhibits excellent chemical stability, reacting almost no with any chemicals and remaining stable in the complex chemical environment of the human body. Furthermore, it has good biocompatibility, preventing immune or inflammatory responses in the body. The fiber optic lamp, connected to the clamp, directly illuminates the sampling forceps head, facilitating more precise manipulation by medical personnel. The miniature camera moves with the sampling forceps head for better control, and its symmetrical arrangement with the fiber optic lamp provides additional assistance during forceps retrieval.

[0014] 2. The metal wire passes through the hollow wire groove to avoid the micro rotary motor, and then through the wire tube to control the closing of the sampling forceps head. This can effectively improve the stability of tissue sampling at the lesion site. The staff can rotate the shaft plate to adjust the sampling connector and the connected parts by the micro rotary motor. This allows for fine adjustments during the tissue sampling process, so as to obtain the most suitable in vivo cells and tissues. Attached Figure Description

The extension hose 6 is made of polytetrafluoroethylene (PTFE). When needed, the PTFE extension hose 6 has an extremely low coefficient of friction, which makes the catheter encounter very little resistance when passing through the endoscope working channel or moving inside the human body. It has excellent chemical stability, hardly reacts with any chemical substances, can remain stable in the complex chemical environment of the human body, and has good biocompatibility, so it will not cause immune or inflammatory reactions in the human body.

[0023] Furthermore, the end of the extension tube 6 is provided with a hollowed-out wire groove 7, and a metal wire 11 is connected to the inner side of the hollowed-out wire groove 7. A wire tube 12 is provided at the outer right side of the metal wire 11, and a clamp 13 is connected to the end of the metal wire 11. A sampling forceps head 14 is provided on the inner side of the clamp 13. The metal wire 11 and the sampling forceps head 14 form a closed structure through the sampling wire drawing motor 3. When needed, the metal wire 11 passes through the hollowed-out wire groove 7, which can avoid the micro rotary motor 8, and then passes through the wire tube 12 to close the sampling forceps head 14. This can effectively improve the stability of tissue sampling at the lesion site.

[0024] Furthermore, a miniature rotary motor 8 is welded to the middle of the hollow wire groove 7, a motor connection kit 9 ​​is welded to the end of the miniature rotary motor 8, and a sampling connector 10 is welded to the outside of the motor connection kit 9. The rotating shaft disk 2 and the miniature rotary motor 8 form a rotation control structure through the electronic controller 1.

[0026] Furthermore, the miniature camera 16 and the fiber optic lamp 15 are symmetrically arranged through the clamp 13, and the miniature camera 16 and the electronic controller 1 are electrically connected with the signal connection line 5. When needed, the miniature camera 16 can move with the sampling forceps head 14, thereby improving control. Moreover, due to the symmetrical arrangement of the miniature camera 16 and the fiber optic lamp 15, it can provide better assistance when the sampling forceps head 14 is performing tweezers.

[0027] Working principle: This endoscopic tissue sampling tool is moved to the working position. In the first step, medical personnel connect it to an external computer via signal cable 5. Then, the extension tube 6 is inserted into the human body through the endoscopic device. Once the appropriate position is reached, the fiber optic light 15 and miniature camera 16 are activated and connected to the electronic controller 1. In the second step, after finding the accurate position, medical personnel control the miniature rotary motor 8 via rotating the shaft disc 2, which drives the motor connection kit 9 ​​and sampling connector 10 to rotate at a micro-angle. After confirming the position, the medical personnel press the wire-pulling button 4. The sampling wire-pulling motor 3 then guides the metal wire 11 inside the extension tube 6 along the hollowed-out wire groove 7 and wire tube 12, driving the sampling forceps head 14 in the clamp 13 to remove the cells and tissue from the human body. The entire tool is then pulled out through the extension tube 6, thus completing the process of using this endoscopic tissue sampling tool.
