Description

Electrocoagulation tweezers with light source Technical Field

[0001] The invention relates to a medical device, in particular to an electrocoagulation tweezers with a light source. Background Art

[0002] Conventional electrocoagulation forceps consist of a tip, an insulated shaft, and an electrode holder. A plug at the rear of the electrode holder connects to an external device via a wire. The tip delivers high-frequency electrical energy to the affected tissue, dehydrating and coagulating the protein between the tips, achieving hemostasis. Because the forceps' action is limited to the area between the tips, damage to adjacent tissues and the affected area is minimal, making them quite safe.

[0003] During use, the light at the site where hemostasis is required is often not very good, and the tweezers tip needs to be carefully observed when pinching, which causes inconvenience to the user. In order to avoid such problems, special personnel are often required to use lighting equipment for illumination, so it is necessary to propose an electrocoagulation tweezers with a light source. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and provide an electrocoagulation forceps with a light source.

[0005] Disclosed is an electrocoagulation tweezers with a light source, comprising a first tweezers rod, a second tweezers rod, an electrode seat, and an adjustable angle light source. The heads of the first tweezers rod and the second tweezers rod are fixedly connected to the motor seat. The first tweezers rod and the second tweezers rod both comprise a tweezers rod body and a tweezers tip. The angle-adjustable light source is sleeved on the outer side wall of the tweezers rod body. The adjustable angle light source comprises an elastic ring, a threaded rod, an annular light ring, and a threaded rod fixing plate. The annular light ring is square. The elastic ring is sleeved on the outer side wall of the tweezers rod body and fits tightly with the outer side wall of the tweezers rod body. The threaded rod fixing plate is fixed above the outer side wall of the elastic ring. The threaded rod is fixed above the threaded rod fixing plate. The annular light ring is arranged at the top of the threaded rod. The threaded rod passes through the annular light ring. The top of the threaded rod is fixedly connected with a fixing nut, and the part of the threaded rod located at the bottom of the annular light ring is threadedly connected with an adjusting nut.

[0006] The present invention fixes the adjustable angle light source on the tweezers rod body through an elastic ring, and the height of the annular light ring can be adjusted front, back, left and right through the threaded rod, so that the adjustable angle light source can adjust the tilt angle, so that the user can fine-tune the light according to needs, without the need for medical staff to use additional light sources to supplement the target area. At the same time, the angle can be adjusted to ensure the lighting needs.

[0007] The present invention uses an elastic ring, which can be a rubber ring, so that the adjustable light source can be installed on the tweezers rod body. If the customer does not need to use the adjustable light source later, the light source can be removed by the customer, which is more humane. At the same time, the elastic ring does not require additional processing on the electrocoagulation tweezers and can be assembled with the electrocoagulation tweezers.

[0008] Preferably, the annular light ring includes a transparent annular shell, the transparent annular shell is provided with an annular groove along the circumferential direction, an LED light strip is provided in the annular groove, and an annular cover is fixedly connected to the top of the annular groove, so that the illumination area is larger through the annular pattern.

[0009] Preferably, the tweezers rod body includes a hand-held portion and a clamping portion, the hand-held portion is provided with a recessed hole, the width of the clamping portion gradually decreases from the head to the tail end, and the elastic ring and the clamping portion have outer dimensions that match each other.

[0010] The present invention can increase the contact area by using the concave hole on the hand-held part, so that the user can firmly hold the electrocoagulation forceps to prevent them from falling off, thereby ensuring the safety of the operation.

[0011] The width of the clamping portion of the present invention is gradually reduced, so that the force is more concentrated and the electrocoagulation is performed better.

[0012] The outer dimensions of the elastic ring and the clamping portion match each other, so that the elastic ring can fit tightly with the clamping portion.

[0013] Preferably, a mounting groove is provided on the inner side of the tail end of the tweezers rod body, a temperature probe is fixed in the mounting groove, and the temperature probe is fixed in the mounting groove by thermal conductive glue.

[0014] The present invention transmits the real-time temperature of the tweezers tip back to the internal chip of the host through a temperature probe. If the temperature is low, the current is increased to increase the temperature of the tweezers tip; if the temperature is high, the current is reduced to reduce the temperature of the tweezers tip. Through such control, the temperature of the tweezers tip will be maintained in the optimal working state, ensuring the effect of blood vessel adhesion.

[0015] Preferably, the inner and outer walls of the tweezers rod body are coated with an electrical insulating paint layer or are covered with a tweezers body cover; the outer wall of the tweezers tip is coated with an electrical insulating paint layer or is covered with an insulating tweezers tip cover, and the inner surface of the tweezers tip is exposed; the outer surface of the insulating tweezers tip cover is insulated, and the inner surface of the insulating tweezers tip cover is exposed;

[0016] The present invention exposes the inner surface of the tweezers tip and insulates the outer surface of the tweezers tip to protect it, thereby reducing the diffusion of current to surrounding tissues and concentrating the energy, thereby saving energy and reducing thermal damage to surrounding tissues.

[0017] When the tweezers tips on both sides act on human tissue, the current will only be transmitted relative to the inner surface of the tweezers tip under the action of the electrical insulating paint, and will not be transmitted in an arc shape along the outer surface from the surrounding tissue, thereby minimizing thermal damage, reducing damage to surrounding tissues, reducing postoperative complications, and shortening postoperative recovery time.

[0018] The inner surface of the tweezers tip is made of an alloy material with electrical and thermal conductivity.

[0082] Working principle:

[0083] As shown in FIG1-13, when the assembly device 5 is used, the elastic ring of the adjustable light source 4 is inserted into the expansion needle 52, and then the expansion electric push rod 561 drives the fixed plate 563 to move upward, and the roller 564 is pushed to the top of the inclined surface, thereby pushing the slider 534 to move along the guide groove 533 to the outside of the fixed block 531, thereby driving the expansion needle 52 to move outward, thereby expanding the inner ring of the elastic ring to a position where the tweezers rod body 11 can be smoothly inserted, and then the first electric push rod 560 moves downward to a specified height, and the clamping part 112 of the tweezers rod body 11 is inserted into the tweezers rod body insertion hole 569. Then, through the inner ring of the expanded elastic ring, the electric push rod 561 is expanded and moved downward, thereby driving the fixed plate 563 to move downward. Since the slider 534 is not subjected to the tightening force of the roller and the spring is provided, the slider 534 rebounds and the expansion needle 52 moves toward the center. Then the lifting plate moves downward, thereby driving the expansion needle 52 to move downward, thereby driving the expansion needle to separate from the elastic ring, thereby completing the installation of the elastic ring and the tweezers rod body 11. After taking out the installed product, the lifting plate returns to its position, driving the expansion needle to return to its position, and the next product is installed. The installation is convenient and fast, reducing defective products caused by manual installation and improving quality.

[0084] When the angle of the light source of the installed electrocoagulation forceps with a light source needs to be adjusted, loosen the adjustment nut and the fixing nut on the side that needs to be adjusted, then move the annular light ring to adjust its position on the threaded rod. After adjusting to the required angle, tighten the adjustment nut and the fixing nut to achieve the tilt of the annular light ring, so that the user can fine-tune the light according to needs, without the need for medical staff to use additional light sources to supplement the illumination of the target area. At the same time, the angle can be adjusted to ensure the lighting needs.
