Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electrocautery forceps. Background Technology

[0002] In the clinical diagnosis and treatment of digestive system diseases, the detection rate of submucosal masses in the gastrointestinal tract (such as stromal tumors, leiomyomas, and lipomas) is increasing year by year. These masses usually originate from the lamina propria, muscularis mucosae, or muscularis propria of the mucosa. They are located deep within the mucosa, have indistinct boundaries with surrounding tissues, and may involve blood vessels or muscular structures, posing significant challenges to traditional endoscopic resection techniques. Currently, the conventional electrothermal biopsy forceps and electric snares widely used in clinical practice are limited in their functionality, making it difficult to achieve complete resection of the masses. This results in problems such as incomplete resection, residual lesions, and even serious complications such as perforation and bleeding due to excessive traction or thermal damage.

[0003] To address the aforementioned issues, current techniques primarily employ endoscopic submucosal dissection (ESD) or modified endoscopic mucosal resection (EMR). However, ESD demands a high level of operator experience, requiring repeated injections of submucosal fluid pads, layer-by-layer dissection of the lesion, and the alternating use of various specialized instruments such as high-frequency electrosurgical units, hook knives, and IT knives. The procedure is complex, time-consuming (typically 1-2 hours), and suffers from limitations such as limited intraoperative visualization and difficulty in controlling the dissection depth. While modified EMR improves tumor resection rates through pre-cutting or segmented resection, it still faces challenges such as tumor fragmentation, difficulties in pathological diagnosis, and an increased risk of recurrence. Furthermore, these methods rely on high-value consumables (such as specialized electrosurgical units and hemostatic clips), significantly increasing medical costs. Utility Model Content

[0004] The purpose of this invention is to provide an electrosurgical forceps to solve the problems existing in the prior art. It can achieve efficient and safe en bloc resection of submucosal tumors without relying on complex consumable combinations, simplifying operation steps, shortening operation time, and reducing the risk of complications such as perforation and bleeding.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an electrocautery forceps, including two forceps flaps. The first ends of the two forceps flaps are hinged to a rotating shaft. The two forceps flaps are joined together to form a complete forceps head. The front of the forceps head is the tumor contact surface, and the tumor contact surface has a concave structure. The forceps flaps are connected to an integrated high-frequency electrogenerator.

[0007] In one embodiment, at least one of the clamping jaws has a notch on its inner side, and when the two clamping jaws are joined together, the notch forms a through hole; when both clamping jaws have notches, the two notches can be joined together to form a through hole.

[0008] In one embodiment, the two clamping lobes are symmetrical, and each clamping lobe is provided with a notch, which is a semi-circular notch.

[0009] In one embodiment, the back of the pliers head is a raised structure, the raised direction of the raised structure is consistent with the concave direction of the concave structure, and the shape of the raised structure is consistent with the shape of the concave structure.

[0010] In one embodiment, the radius of curvature of the recessed structure is 3 mm to 5 mm, and the radius of the semi-circular notch is 4 mm to 6 mm.

[0011] In one embodiment, the device further includes an insulating handle for driving the clamping jaws, the driving end of the handle being provided with a pull ring, and the driven end of the insulating handle being connected to the clamping jaws.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2As shown, this utility model provides an electrocautery forceps, including two forceps 1. The first ends of the two forceps 1 are hinged to a rotating shaft 2. The two forceps 1 are joined to form a complete forceps head. The front of the forceps head is the tumor contact surface, which has a concave structure. The forceps 1 are connected to an integrated high-frequency electrocautery generator 8. The two forceps 1 rotate around the rotating shaft 2 to achieve cutting. The concave tumor contact surface can conform to the tumor surface and match the tumor contour. During resection, the two forceps 1 can move along the outer edge of the tumor contour, avoiding the problem of multiple resections caused by the tumor obstructing the movement of the forceps 1. Resection can be performed in one go simply by following the image captured by the endoscope, without the need for other auxiliary fixation and traction devices. After resection, the integrated high-frequency electrocautery generator 8 passes a high-frequency current to the forceps 1 for electrocoagulation hemostasis, without the need for other hemostatic devices to participate in the resection.

[0031] In one embodiment, at least one clamp flap 1 has a notch 3 on its inner side. When two clamp flaps 1 are joined together, the notch 3 forms a through hole. When both clamp flaps 1 have notches 3, the two notches 3 can be joined together to form a through hole. The notch 3 can guide high-frequency current to pass more concentratedly through the target tissue, avoiding energy diffusion and reducing surrounding thermal damage during electrocoagulation. The notch 3 can also increase the friction between the clamp flap 1 and the tissue, preventing slippage during clamping, and can also avoid excessive compression of the tissue when the clamp flaps 1 are fully closed. The notch 3 can also allow blood, tissue fluid, or vapor generated by electrocoagulation to escape during clamping, preventing pressure buildup from affecting the field of vision or operation.

The forceps head as a whole has a spoon-shaped structure, and the back of the forceps head is also relatively rounded without sharp edges, so that the back of the forceps head will not damage the non-lesion areas it contacts during movement.

[0034] In one embodiment, the radius of curvature of the recessed structure is 3 mm to 5 mm, and the radius of the semi-circular notch is 4 mm to 6 mm.

[0035] In one embodiment, an insulating handle 4 is further included for moving the clamp flaps 1. The active end of the handle 4 is provided with a pull ring 5, and the driven end of the insulating handle 4 is connected to the clamp flaps 1. During surgery, the insulating handle 4 connected to the clamp flaps 1 is inserted into the patient's body until the clamp flaps 1 reach the lesion. Then, the pull ring 5 is controlled to move the insulating handle 4 to open the clamp flaps 1. The insulating handle 4 is then controlled to move so that the tissue to be cut is located in the opening formed by the two clamp flaps 1. The pull ring 5 is then operated to close the two clamp flaps 1 to complete the cutting. After cutting, a high-frequency current is passed through the clamp flaps 1 for electrocoagulation hemostasis.
