Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to a pair of dripping bipolar electrocoagulation forceps for endoscopic lateral skull base surgery. Background Art

[0002] Bipolar electrocoagulation forceps can be used for more precise electrocoagulation hemostasis and treatment of small blood vessels and other structures. The principle is to heat the protein to coagulate the blood vessels and close the tissue. When the tissue is heated to the coagulation and boiling point, the power can be automatically cut off. At the same time, because the blades of the bipolar electrocoagulation forceps are insulated, the current is only conducted between the tips of the forceps. During electrocoagulation, the current flows from one tip to the other. The tissues at the two tips are affected by the thermal effect of the current, while the tissues outside the tips are less affected or not affected, which has a protective effect on the brain tissue. Bipolar electrocoagulation forceps also have functions such as separation and clamping. Bipolar electrocoagulation forceps have a flushing channel. The flushing effect can reduce the heat generated by electrocoagulation and prevent the electrocoagulated tissue from adhering to the tip of the bipolar electrocoagulation. Bipolar electrocoagulation plays a special role in the shaping of the aneurysm neck during aneurysm surgery and the success or failure of the surgery.

[0003] During the operation, blood will gush out, affecting the surgeon's vision, so bipolar electrocoagulation forceps are needed for electrocoagulation hemostasis. The existing bipolar electrocoagulation forceps first use gravity to make water droplets flow out naturally from the tip of the bipolar electrocoagulation forceps, thereby reducing the heat generation effect of electrocoagulation. Secondly, they are mostly used for surgical operations under a microscope. The bipolar action end and the handheld body are straight and have no angle. It can only be performed in an open surgical cavity and under a straight field of view. In lateral skull base endoscopic surgery, it is often necessary to use the wide-angle and multi-angle characteristics of the endoscope. There is no need to open the surgical cavity, and important structures can be bypassed for surgical operations. In this case, bipolar electrocoagulation hemostasis is required to have two characteristics: (1) The tip of the bipolar electrocoagulation forceps has a variety of angles, which can keep important anatomical structures in place while treating hidden lesions and stopping bleeding around them. (2) Because it is necessary to keep important anatomical structures in situ and avoid displacement and opening, when stopping bleeding and treating lesions, the water outlet at the tip of the angled bipolar electrocoagulation forceps needs to overcome the influence of gravity in order to achieve water outlet and cooling. This makes it difficult for the conventional bipolar electrocoagulation water outlet method to meet the needs.

[0004] Therefore, how to solve the above two problems is a key technical problem that technicians in this field need to solve. Summary of the invention

[0037] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices or methods consistent with some aspects of the present application.

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0040] refer to Figure 1-14 The present specific embodiment provides a water-drip bipolar electrocoagulation forceps for lateral skull base surgery endoscope, comprising two forceps bodies and an electrode holder 1, the tail ends of the two forceps bodies are electrically connected to the electrode holder 1, and the two forceps bodies include a forceps rod and a tip 5 connected to the head end of the forceps rod, the outer surface of the forceps rod is provided with an insulating sleeve, the tip 5 of the two forceps bodies protrudes from the insulating sleeve and is exposed to facilitate conduction, and a water channel is provided in the two forceps rods, the water channel is provided along the extension direction of the forceps body, and the water outlet is close to the tip 5 of the forceps body. It is arranged so that the physiological saline solution in the water channel can flow along the tip 5 to the bleeding tissue, wherein the dripping bipolar electrocoagulation forceps for lateral skull base surgery endoscopy also include a pressure pump 2, which is arranged at the tail end of the forceps body, that is, the pressure pump 2 is arranged at the tail end of the forceps rod, and the water inlet of the pressure pump 2 is used to be connected to the water supply catheter, and the water outlet of the pressure pump 2 is connected to the water inlet of the water channel to introduce the physiological saline solution in the water supply catheter into the water channel, thereby flowing into the bleeding tissue through the water outlet 6 of the water channel.

[0041] The dripping bipolar electrocoagulation forceps used for endoscopic skull base surgery utilize a pressure pump 2 to introduce the saline solution in the water delivery catheter into the water channel of the forceps body, thereby increasing the water outflow of the saline solution and forming a water flow, thereby flushing the blood in the bleeding tissue, providing the surgeon with a clearer field of vision during the operation, facilitating the surgeon's operation, and improving the efficiency of the operation.

[0042] Moreover, the tip 5 is arranged at an angle with the forceps shaft or the tip is bent relative to the forceps shaft, that is, the tip 5 is bent relative to the forceps shaft, so that in the lateral skull base endoscopic surgery, the wide-angle and multi-angle characteristics of the endoscope are matched, and the surgical operation can be performed by bypassing important structures without opening the surgical cavity, and the surrounding hidden lesions and hemostasis operations can be handled while keeping important anatomical structures in place. During the operation, the operator can choose different forceps according to the actual situation, so that the operator can reach into some corners through the electrocoagulation forceps to adapt to any complex situation and improve the efficiency of the operation.

[0043] Such an arrangement solves the problem that the tip of the existing bipolar electrocoagulation forceps cannot meet the requirements of various angles and the water outlet method is difficult to meet the requirements.

[0044] In a preferred solution of this embodiment, the pressure pump 2 is detachably connected to the forceps body, so that it is easy to determine whether the pressure pump 2 needs to be used according to actual conditions.

[0045] It should be noted that the tweezers body here can be an integral structure, that is, the tweezers body is formed in one piece during production.

[0046] Specifically, Figure 1 As shown, the water outlet of the booster pump 2 can be connected to the water inlet of the water channel through a water conduit. In addition, the change in the diameter of the booster pump 2 and the water channel inside the forceps body and the overall shape of the water channel determine the water outlet pressure and flow rate of the forceps tip. The water outlet pressure and flow rate of the forceps tip can be adjusted by adjusting the diameter of the booster pump 2 or the water channel or the overall shape of the water channel, and the adjustment is made according to the actual situation.

[0047] The booster pump 2 may be connected to the water pipe on the electrode holder. It is known that the electrode holder is provided with a high-frequency input line 15 and a water pipe 14 connected to the water channel, and the high-frequency input line 15 and the water pipe 14 are separated.

[0048] In the preferred embodiment of this embodiment, Figure 1As shown, the tweezers rod includes a first tweezers body 3 and a plurality of second tweezers bodies 4, wherein the tail end of the first tweezers body 3 is connected to the electrode holder 1, and the tail ends of the plurality of second tweezers bodies 4 can be detachably connected to the head end of the first tweezers body 3, and the tip portion 5 is located at the head end of the second tweezers body 4 and is an integrated structure with the second tweezers body 4, wherein the second tweezers body 4 and the tip portion 5 form an angle, and the angles between the plurality of second tweezers bodies 4 and the tip portion 5 are of different sizes, so that the tip portions 5 of the plurality of second tweezers bodies 4 are bent at different angles.

[0049] In this way, during the operation, the surgeon can select different second forceps bodies 4 according to the actual situation, so as to facilitate the surgeon to extend the electrocoagulation forceps into some crooked positions, so as to adapt to any complex situation and improve the efficiency of the operation.

[0050] Specifically, Figure 2 As shown, the forceps rod portion may include a second forceps body 4 with an angle of 0 degrees with the tip portion 5, that is, the tip portion 5 is not bent relative to the second forceps body 4; multiple second forceps bodies 4 with an angle greater than 0 degrees and less than 180 degrees with the tip portion 5, such as Figure 4 As shown, the included angles between the second forceps bodies 4 and the tip portion 5 can be 30 degrees, 60 degrees, 90 degrees, 150 degrees, etc.

[0051] It should be noted that the first forceps body 3 can be the part of the forceps body excluding the tip 5 (i.e., the forceps rod part), and the second forceps body 4 is the tip 5. Figure 1 As shown, a protrusion 8 for preventing the two tweezers from sticking together is provided on one opposite side of the two tweezers bodies, and the first tweezers body 3 can be a straight segment, the second tweezers body 4 can be a "Z"-shaped structure, and the protrusion 8 is located on the second tweezers body 4, that is, the connection between the first tweezers body 3 and the second tweezers body 4 is located on the side of the protrusion 8 away from the tip 5. Of course, the protrusion 8 can also be provided on the first tweezers body 3, that is, the connection between the first tweezers body 3 and the second tweezers body 4 is located on the side of the protrusion 8 close to the tip 5. Specifically, the connection between the first tweezers body 3 and the second tweezers body 4 can be at any position of the tweezers body except the tip 5.

[0052] In other embodiments, the second forceps body 4 is curved as a whole, such as Fig.14 As shown, the bending direction of the second tweezers body 4 is parallel to the extension direction of the tweezers body; or the second tweezers body 4 is inclined relative to the first tweezers body 3, and the inclination direction is parallel to the extension direction of the tweezers body, that is, the second tweezers body 4 and the first tweezers body 3 are located in the same plane, which is convenient for reaching into various narrow spaces to perform surgical operations as needed.

[0053] In this embodiment, a first insulating sleeve is provided outside the first tweezers body 3, and a second insulating sleeve is provided outside the second tweezers body 4. In order to match the first tweezers body 3 and the second tweezers body 4, the head end of the first insulating sleeve and the tail end of the second insulating sleeve can also be detachably connected.

[0054] In some embodiments, Figure 1 As shown, the head end of the first insulating sleeve and the tail end of the second insulating sleeve are connected by a quick connector 7, so as to quickly connect the first insulating sleeve and the second insulating sleeve, thereby connecting the first tweezers body 3 and the second tweezers body 4.

[0055] Among them, Figure 6 and Figure 7 As shown, the quick connector 7 includes a third insulating sleeve 9 and a third tweezer body 10 fixedly arranged on the inner wall of the third insulating sleeve 9. The length of the third tweezer body 10 is less than that of the third insulating sleeve 9 and is located in the middle position of the inner wall of the third tweezer body 10. The head end of the first insulating sleeve and the tail end of the second insulating sleeve can respectively extend into the two ends of the third insulating sleeve 9, even if the two ends of the third insulating sleeve 9 are respectively sleeved outside the head end of the first insulating sleeve and the tail end of the second insulating sleeve, the two ends of the third tweezer body 10 are respectively connected and aligned with the head end of the first tweezer body 3 and the tail end of the second tweezer body 4, so that the first tweezer body 3 and the second tweezer body 4 are connected, so that the first tweezer body 3 can conduct current to the second tweezer body 4 through the third tweezer body 10.

[0056] And, if Figure 6 As shown, a through groove 11 is provided on the third tweezers body 10, and the through groove 11 is arranged along the extension direction of the third tweezers body 10, that is, along the axial direction of the third insulating sleeve 9. After the third tweezers body 10 is docked with the first tweezers body 3 and the second tweezers body 4, the through groove 11 is connected with the water channel of the first tweezers body 3 and the water channel of the second tweezers body 4, so that physiological saline can flow from the water channel of the first tweezers body 3 into the second tweezers body 4, and then flow into the bleeding tissue.

[0057] In order to ensure that the first insulating sleeve and the second insulating sleeve can be tightly connected, the head end of the first insulating sleeve and the tail end of the second insulating sleeve are tightly matched with the two ends of the third insulating sleeve 9 respectively, so as to prevent the second insulating sleeve from detaching from the first insulating sleeve and becoming unusable.

[0058] Preferably, protrusions are provided on the outer walls of the head end of the first insulating sleeve and the tail end of the second insulating sleeve, and slots 12 are provided on the inner walls of both ends of the third insulating sleeve 9. The protrusions can be embedded in the slots 12 and match with the slots 12, thereby improving the stability of the connection between the third insulating sleeve 9 and the first insulating sleeve and the second insulating sleeve.

[0059] Here, the protrusion may be an annular protrusion, and the groove 12 may be an annular groove matching the protrusion, so as to further improve the stability of the connection between the third insulating sleeve 9 and the first insulating sleeve and the second insulating sleeve.

[0060] In order to prevent saline from flowing out from the connection between the first insulating sleeve and the second insulating sleeve, a sealing ring is provided at the connection between the first insulating sleeve and the second insulating sleeve, that is, sealing rings can be provided at the connection between the first insulating sleeve and the third insulating sleeve 9 and the second insulating sleeve and the third insulating sleeve 9.

[0061] In other embodiments, the head end of the first tweezers body 3 and the tail end of the second tweezers body 4 may be plugged into each other. Specifically, Figure 8 As shown, a slot is provided at the head end of the first tweezers body 3, and an insert 13 is provided at the tail end of the second tweezers body 4, and the slot and the insert 13 are both arranged along the extension direction of the tweezers bodies. The insert 13 can be inserted into the slot and fit tightly with the slot to connect the first tweezers body 3 and the second tweezers body 4, which facilitates the installation and disassembly of the first tweezers body 3 and the second tweezers body 4.

[0062] Here, the length of the insert 13 is the same as the length of the slot, so that after the insert 13 is fully inserted into the slot, the head end of the first tweezers body 3 and the tail end of the second tweezers body 4 fit together.

[0063] Figure 9-Figure 14 The electrocoagulation forceps have forceps bodies of different styles and shapes, and Figure 9-Figure 14 The tip of the forceps is bent into different angles, and doctors can choose different electrocoagulation forceps according to their needs.
