Description

Technical Field

[0001] This invention relates to the medical field, and more particularly to a snare device for use in digestive endoscopy. Background Technology

[0002] Currently, the snares widely used in the market are all coil snares, which are more convenient when snares are relatively small or when the location of the polyp is easy to snare.

[0003] However, existing snare devices have the following drawbacks:

[0004] 1. When encountering larger polyps, the diameter of the snare needs to be adjusted according to the size of the polyp, which is not very convenient;

[0005] 2. When polyps are located at corners or in complex locations in the digestive tract, it is often impossible to completely snare the polyp satisfactorily or to complete the snare in a short time, no matter how the snare angle is adjusted or the endoscope direction is changed. This greatly increases the time for endoscopic polyp removal, reduces surgical efficiency, and also increases the risk of anesthesia for the patient. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a snare for use in digestive endoscopy, which can solve the problems of inconvenience and low efficiency.

[0007] One of the objectives of this invention is achieved through the following technical solution:

[0008] A snare device for use in digestive endoscopy includes a snare assembly and an operating component that works in conjunction with the snare assembly. The snare assembly includes a resin clamp, a spring, a connecting hole, a metal wire, and a baffle. The spring is mounted on the resin clamp, which has a connecting hole for fixing the metal wire. A baffle is provided at the end of the resin clamp. The operating component includes a snare assembly base, a resin clamp operating rod, a resin clamp release rod, a resin clamp operating rod handle, and a metal wire operating handle. The resin clamp release rod passes through the resin clamp operating rod in the middle and passes through the snare assembly base. The metal wire passes through the snare assembly base and is connected to the metal wire operating handle. The metal wire base assembly and the resin clamp base are mounted on the snare assembly base. The resin clamp operating rod handle is adjusted to position the resin clamp appropriately. Pulling the resin clamp release rod causes the baffle to dislodge, the spring to retract, and the resin clamp to be fixed to the intestinal wall mucosa, i.e., one end of the metal wire is fixed. The metal wire operating handle is used to make the other end of the metal wire move around the bottom of the polyp, tightening it and forming a closed loop with the metal wire connected to the resin clamp.

[0009] Furthermore, the resin clip includes two clamping arms, and the spring is disposed between the two clamping arms.

[0010] Furthermore, the base of the snare device is located on the side of the operating component.

[0011] Furthermore, the base of the snare device is cylindrical.

[0012] Furthermore, the resin clamp operating rod is hollow inside, and the length of the resin clamp release rod is greater than that of the resin clamp operating rod.

[0013] Furthermore, the resin clamp is fixed to the end of the resin clamp operating rod and the resin clamp release rod by means of the baffle to keep it in an open state.

[0014] Furthermore, the wire base assembly includes a wire metal base and a wire resin base, with the wire metal base disposed on the wire resin base.

[0015] Furthermore, the volume of the metal wire base is smaller than that of the metal wire resin base.

[0016] Furthermore, the metal wire operating handle is equipped with a power button.

[0017] Furthermore, the wire operating handle is also equipped with a power supply that works in conjunction with the power button.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The operating components include a snare device base, a resin clamp operating rod, a resin clamp release rod, a resin clamp operating rod handle, and a metal wire operating handle. The resin clamp release rod passes through the resin clamp operating rod and connects to the end baffle of the resin clamp. The resin clamp operating rod passes through the snare device base and the mounting end. The metal wire passes through the snare device base and the mounting end and connects to the metal wire operating handle. The metal wire base assembly and the resin clamp resin base are installed on the snare device base. The resin clamp operating rod handle is adjusted to position the resin clamp appropriately. Pulling the resin clamp release rod causes the baffle to detach, the spring to retract, and the resin clamp to be fixed to the intestinal wall mucosa, i.e., one end of the metal wire is fixed. The metal wire operating handle is used to make the other movable end of the metal wire wrap around the bottom of the polyp, tighten it, and then form a closed loop with the metal wire connected to the resin clamp. The device of this application can overcome the shortcomings of traditional snares. When the resin clamp is fixed to the intestinal wall mucosa, one end of the metal wire is fixed. The other end of the metal wire is moved around the bottom of the polyp by operating the handle through the metal wire. After tightening, it forms a closed loop with the metal wire connected to the resin clamp. When energized, it can remove polyps that are as large as possible or polyps in difficult locations under endoscopy. This provides a new option to address the shortcomings of traditional snares under endoscopy. This invention makes the removal of large polyps or polyps in difficult locations under endoscopy more convenient and faster, improves surgical efficiency, and also improves the safety of patients during surgery.

The resin clamp release rod 22 passes through the resin clamp. The clamping operating rod 21 is connected to the end baffle 15 of the resin clamp. The resin clamp operating rod 21 passes through the snare device base 19. The metal wire 14 passes through the snare device base 19 and is connected to the metal wire operating handle 24. The metal wire base assembly and the resin clamp resin base 18 are installed on the snare device base 19. The resin clamp operating rod handle 23 is adjusted to make the resin clamp 11 in a suitable position. The resin clamp release rod is pulled to make the baffle fall off and the spring retracts. The resin clamp is fixed to the intestinal wall mucosa, i.e., one end of the metal wire is fixed. The other end of the metal wire is moved around the bottom of the polyp by the metal wire operating handle 24. After tightening, it forms a closed loop with the metal wire 14 connected to the resin clamp 11. The device of this application can overcome the shortcomings of traditional snares. When the resin clamp is fixed to the intestinal wall mucosa, one end of the metal wire is fixed. The other end of the metal wire is moved around the bottom of the polyp by operating the handle through the metal wire. After tightening, it forms a closed loop with the metal wire connected to the resin clamp. When energized, it can remove polyps that are as large as possible or polyps in difficult locations under endoscopy. This provides a new option to address the shortcomings of traditional snares under endoscopy.

The entire device has a compact structure, novel design, ingenious design, strong applicability, and is easy to promote.

[0031] Working principle: When a polyp is found, first adjust the resin clamp operating lever handle 23 to adjust the direction of the resin clamp 11. Then, slightly pull the resin clamp loosening lever 22 near the bottom of the polyp's intestinal mucosa to allow the baffle 15 to detach. The spring 12 returns to its original shape, causing the resin clamp 11 to clamp and fix itself to the intestinal mucosa, thus securing one end of the metal wire connected to the connecting hole. Next, operate the entire snare system and adjust the direction of the metal wire operating handle 24 so that the metal wire wraps around the base of the polyp. Finally, tighten the metal wire 14 using the metal wire operating handle 24, causing the metal wire base 16 to engage with the fixed end of the metal wire 14 connected to the resin clamp 11, forming a closed loop. After turning on the power button 25 and power supply 26, the polyp is removed.
