Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a novel plasma cutter for surgery. Background Art

[0002] A plasma resectoscope is a medical device used to cut and coagulate tissue during surgery. The principle is to use high-frequency current to generate plasma in the tissue, and the high temperature generated by the plasma is used to achieve cutting and coagulation. Compared with traditional surgical knives, a plasma resectoscope has more precise cutting and coagulation capabilities, and can handle tissue more delicately during surgery, reducing the risk of bleeding and damage to surrounding tissues. It is widely used in various surgeries, including general surgery, urology surgery, plastic surgery, etc., providing doctors with an efficient and safe surgical tool, while also improving the success rate of surgery and the speed of patient recovery.

[0003] At present, the plasma resectoscopes used for prostate hypertrophy resection surgery on the market are generally designed as a single integral structure. This design ensures the integrity of the device and stability during operation, but these single-body plasma resectoscopes have some limitations. On the one hand, because the cutter head is tightly fixed to the device body, once the cutter head part is worn or damaged, it cannot be easily disassembled and replaced on site for repair. It may need to be replaced as a whole or sent back to the manufacturer for repair, which increases the time of surgical suspension and maintenance costs; on the other hand, considering that these resectoscopes use a single-layer cutting ring design, for soft tissues with larger diameters or larger volumes, such as prostate hypertrophy tissue, a single-layer cutting ring is difficult to complete the resection in one go, which results in a slower cutting speed and increased surgical time.

[0004] Therefore, when performing large-volume soft tissue resection, the efficiency and applicability of these single-body plasma resectors still have room for improvement. Based on this, we propose a new type of plasma resector for surgery to solve the above-mentioned problems. Utility Model Content

[0005] In order to improve the above-mentioned problems, the utility model provides a new type of plasma cutter for surgery.

[0006] The utility model provides a new type of plasma cutter for surgery, which adopts the following technical scheme: a new type of plasma cutter for surgery, comprising a gripping assembly and a cutting blade head, wherein the cutting blade head is mounted at one end of the gripping assembly, wherein the gripping assembly comprises an insulating protective sleeve and a metal conductive component for prostate hypertrophy cutting surgery, wherein the outer sleeve of the metal conductive component is provided with an insulating protective sleeve;

[0007] The cutting blade head comprises a mounting component and a cutting component for prostate hypertrophy cutting surgery, and the cutting component is connected between one ends of two groups of mounting components.

[0008] Based on the above technical features: the new plasma cutter designed in this scheme has made innovations on the basis of the traditional plasma cutter technology, mainly improving the structure and configuration of the cutting head. The cutter includes a gripping assembly and a cutting head. The cutting head is installed at one end of the gripping assembly to provide good operability and flexibility. The gripping assembly is composed of an insulating protective cover and a metal conductive part. The insulating protective cover can be used to protect the surgical personnel from electric current damage and ensure surgical accuracy, while the metal conductive part is used to conduct current to the cutting head to generate plasma and perform cutting actions.

[0009] In addition, the core design of the cutting head is that it has two sets of annular cutting structures, namely a first metal cutting ring and a secondary second metal cutting ring. This double-ring design enables the cutting head to cut a larger volume of prostate tissue in fewer processes, thereby improving surgical efficiency. The double-ring structure in this scheme also allows the cutting head to be detachably connected and repaired and replaced, thereby reducing maintenance costs and shortening surgical interruption time caused by cutting head repair. The design of the metal conductive component includes a first support member and a second support member, which enhances the stability of the entire electrosurgical cutter and also facilitates the replacement and adjustment of the head.

[0010] As a new type of plasma cutter for surgery described in the utility model, wherein: the cutting component includes a first metal cutting ring, and a second metal cutting ring is arranged on one side of the first metal cutting ring.

[0011] Based on the above technical features: the structural design of this double-layer cutting ring effectively improves the performance of the new plasma cutter for surgery, especially in large-volume tissue resection surgery, and can provide more efficient and safer surgical solutions.

[0012] As a new type of plasma cutter for surgery described in the utility model, wherein: the metal conductive component includes a first support member, and a second support member is arranged on one side of the first support member.

[0013] Based on the above technical features: the metal conductive component in this solution is composed of a first support member and a second support member, which enhances the stability of the entire electric cutter and also facilitates the replacement and adjustment of the blade head.

[0014] As a new type of plasma cutter for surgery described in the utility model, the first support member and the second support member have the same structure, and the first support member and the second support member are both composed of metal straight rods and metal bent rods, and positioning clamps are respectively provided on both sides of one end of the two groups of metal bent rods.

[0015] Based on the above technical features: the design of this part greatly increases the reliability and convenience of the plasma cutter during surgery, while reducing the complexity and cost of long-term use and maintenance.

[0016] As a novel plasma cutter for surgery described in the utility model, the mounting component comprises a conductive base, and a positioning slot is provided at the bottom of the conductive base.

[0017] Based on the above technical features: This solution uses a positioning slot opened at the bottom of the conductive base to be used for the disassembly and assembly connection between the cutting head and the gripping assembly.

[0018] As a novel plasma cutter for surgery described in the utility model, wherein: the positioning slot matches the positioning clamping head structure, and the positioning slot and the positioning clamping head are in a clamping fit.

[0019] Based on the above technical features: Through the structural design of the card-fitting between the positioning slot and the positioning card head, the holding assembly can detachably connect and repair and replace the cutting head according to the usage, thereby reducing the maintenance cost of the plasma cutter.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] 1. The innovative design of the new plasma resectoscope is mainly optimized for prostate hypertrophy resection surgery. The traditional single-layer cutting ring resectoscope is inefficient when cutting large volumes of tissue, which prolongs the operation time. The double-layer cutting ring design of this solution greatly enhances the surgical performance, can more quickly remove larger soft tissues, effectively shorten the operation time, reduce the patient's anesthesia risk and the amount of bleeding during the operation; the cutting head in this solution adopts a detachable structure design, which makes maintenance and replacement more convenient, reduces the downtime of the resectoscope caused by damage to the cutting head, and greatly reduces the operation interval time and the hospital's maintenance cost for such instruments;

[0022] 2. In addition, the double support design enhances the stability of the entire cutting unit, ensuring the accuracy and safety of the cutting action during the operation. In addition, the use of insulating protective sleeves further improves the safety of the operation. Therefore, this new plasma cutter not only improves surgical efficiency, but also has a positive impact on patient safety and postoperative recovery. BRIEF DESCRIPTION OF THE DRAWINGS
