技术领域Technical field
本发明涉及医疗器械技术领域，更具体地说，它涉及一种具有多功能的高频刀具。The present invention relates to the technical field of medical devices, and more specifically, to a high-frequency tool with multiple functions.
背景技术Background technique
随着内镜治疗的广泛发展，某些领域下的传统外科手术越来越多地被内镜下手术替代，内镜下手术具有创伤小、并发症少等明显优势，如内镜下组织活检、内镜下黏膜切除术(Endoscopic mucosal resection，EMR)、内镜下黏膜剥离术(Endoscopic submucosaldissection，ESD)等常用术式也经过了时间的检验，已被大量应用。高频电刀作为必不可少的手术器械，用于剥离黏膜，实现病变组织整块切除。With the widespread development of endoscopic treatment, traditional surgeries in certain fields are increasingly being replaced by endoscopic surgeries, which have obvious advantages such as less trauma and fewer complications, such as endoscopic tissue biopsy. , endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD) and other common surgical procedures have also passed the test of time and have been widely used. As an indispensable surgical instrument, high-frequency electrosurgery is used to peel off mucosa and achieve en bloc resection of diseased tissue.
市面上的高频电刀通常不含注水功能，而手术中患者消化道分泌的粘液以及手术中产生的血污经常阻挡医生视野，使得病变组织难以被清晰观察、无法准确下刀进行切割。现在，越来越多的内镜自带水气阀门，可用于清洗粘液及血污，但主要用于清洗软性内镜头端镜头及光源，因水压不足且水量过小无法用于病患消化道地清洗。目前针对消化道清洁主要还是内镜钳道内注射生理盐水，这就造成了术中反复更换器械的现象，大大增加手术时间，给患者带来了痛苦。High-frequency electrosurgical scalpels on the market usually do not have a water-injection function, and the mucus secreted by the patient's digestive tract and the blood stains produced during the operation often block the doctor's field of vision, making it difficult to clearly observe the diseased tissue and prevent accurate cutting. Nowadays, more and more endoscopes are equipped with water and air valves, which can be used to clean mucus and blood stains. However, they are mainly used to clean the soft endoscope lens and light source. Due to insufficient water pressure and too small water volume, they cannot be used for patient digestion. Authentic cleaning. At present, the main method for cleaning the digestive tract is to inject normal saline into the endoscopic forceps channel, which results in repeated changes of instruments during the operation, greatly increases the operation time, and brings pain to the patient.
目前市场上常用的器械主要是单功能的电切器械，极少厂家提供切割、喷液整合功能的器械。申请公布号为CN109394335A的中国专利公开了高频复合电刀，其为切割、喷液二合一器械，使用滑动把手通过钢绳导电和驱动推拉刀杆，实现切割、标记，使用过程中刀头或刀杆总是会裸露，给手术造成风险。Currently, the commonly used instruments on the market are mainly single-function electrosurgical instruments, and few manufacturers provide instruments with integrated cutting and liquid spraying functions. The Chinese patent application publication number CN109394335A discloses a high-frequency composite electric knife. It is a two-in-one cutting and liquid spraying instrument. It uses a sliding handle to conduct electricity through a steel rope and drive and push the knife rod to achieve cutting and marking. During use, the knife head Or the blade will always be exposed, posing risks to the operation.
授权公布号为CN209107567U的中国专利公开了一种多功能高频电切开刀，其为电凝、注射、切割三合一器械，其中，电凝功能采用钳子杯夹闭结构，其操作繁琐，结构较复杂，制造成本高。The Chinese patent with the authorized publication number CN209107567U discloses a multifunctional high-frequency electrostomy knife, which is a three-in-one instrument for electrocoagulation, injection, and cutting. Among them, the electrocoagulation function uses a clamping cup clamping structure, and its operation is cumbersome. The structure is complex and the manufacturing cost is high.

The syringe is fixed at the injection interface 16, and the liquid can be sprayed from the front end of the O-knife 11;
切割功能：如图2、图3和图4所示，推动外鞘管21向前移动，使外鞘管21包裹住导电座14；将第二手柄沿第一手柄35向前推动，第二手柄向前移动并带动注射管23以及O刀11向前移动，使O刀11从外鞘管21的前端伸出，此时，连接器34、弹簧管22、导电座14、导电移动块以及O刀11形成一个连通电路，将高频电连接到连接器34上，进行O刀11切割操作；Cutting function: As shown in Figure 2, Figure 3 and Figure 4, push the outer sheath 21 forward so that the outer sheath 21 wraps the conductive seat 14; push the second handle forward along the first handle 35, and the second The handle moves forward and drives the injection tube 23 and the O-knife 11 to move forward, so that the O-knife 11 extends from the front end of the outer sheath tube 21.

At this time, the connector 34, the spring tube 22, the conductive base 14, and the conductive moving block And the O knife 11 forms a connected circuit, connects the high frequency electrically to the connector 34, and performs the O knife 11 marking operation.
医生可以根据需要进行相应的操作，即可对病变组织进行标记；又可喷射生理盐水对人体组织进行清洗；还可以切割剥离粘膜组织；如此节省了更换器械的时间，提高了手术效率，最大限度的减少了病人的痛苦。Doctors can perform corresponding operations as needed, including marking diseased tissue; spraying saline to clean human tissue; and cutting and peeling off mucosal tissue. This saves the time of changing instruments, improves surgical efficiency, and maximizes surgical efficiency. Reduce the patient's pain.
在初始状态时，即外鞘管21包裹住导电座14，同时O刀11收回至导电座14内仅露出O刀11刀头，该刀具不需要进行额外驱动件的驱动即可实现喷液功能以及标记功能，减少了医生的操作步骤，提高了手术效率，在进行电切割功能时，仅需要推动第二手柄沿第一手柄向前移动，使O刀11从外鞘管21的前端伸出，同时将高频电连接到连接器34上，即可进行O刀11切割操作，其操作较简单方便，不容易出现误操作现象。In the initial state, that is, the outer sheath tube 21 wraps the conductive seat 14, and at the same time, the O-knife 11 is retracted into the conductive seat 14 and only the O-knife 11 head is exposed. The tool does not need to be driven by an additional driving member to realize the liquid spraying function. And the marking function reduces the doctor's operating steps and improves the surgical efficiency. When performing the electric cutting function, it is only necessary to push the second handle forward along the first handle to make the O knife 11 extend from the front end of the outer sheath tube 21 , and at the same time, connect the high-frequency electricity to the connector 34 to perform the O-knife 11 cutting operation. The operation is simple and convenient, and it is not prone to misoperation.
为了进一步提高该高频刀具的实用性，外鞘管21的后端与第一手柄滑动连接，外鞘管21向后运动并露出导电座14。如此，在上述技术方案的基础上进行了优化，增加了电凝功能；电凝功能：如图9和图10所示，拉动外鞘管21向后移动，使导电座14裸露；将第二手柄沿第一手柄向后拉动，第二手柄向后移动并带动注射管23以及O刀11向后移动，使O刀11收回至导电座14内仅露出O刀11刀头，此时，连接器34、弹簧管22、导电座14以及导电移动块形成一个连通电路，进行电凝功能。在电凝和电切割功能之间通过对应驱动件的反向运动，以此首先可以完全消除待命功能的意外启动，避免对病人造成意外伤害或对手术过程造成干扰。In order to further improve the practicality of the high-frequency tool, the rear end of the outer sheath 21 is slidably connected to the first handle, and the outer sheath 21 moves backward to expose the conductive base 14 . In this way, the above technical solution has been optimized and the electrocoagulation function has been added; the electrocoagulation function: as shown in Figures 9 and 10, pull the outer sheath 21 to move backward to expose the conductive seat 14; The handle is pulled backward along the first handle, and the second handle moves backward and drives the injection tube 23 and the O knife 11 to move backward, so that the O knife 11 is retracted into the conductive base 14 and only the head of the O knife 11 is exposed. At this time, the connection The device 34, the spring tube 22, the conductive base 14 and the conductive moving block form a connected circuit to perform the electrocoagulation function. Through the reverse movement of the corresponding driving parts between the electrocoagulation and electrocution functions, the accidental activation of the standby function can be completely eliminated to avoid accidental injury to the patient or interference with the surgical process.
进一步的，如图5和图6所示，外鞘管21的后端固定有外鞘移动块31，外鞘移动块31的后端与第一手柄35插套滑动连接。外鞘管21通过外鞘接头24与外鞘移动块31固定连接，外鞘接头24的外周壁形成齿状，外鞘管21套接在外鞘接头24的外周壁上。如此，方便外鞘管21与第一手柄的组装。作为优选，外鞘移动块31向后移动至与第一手柄相抵并露出导电座14。如此，外鞘移动块31向后移动至与第一手柄相抵并限制外鞘管21进一步的向后移动，使导电座14完全暴露在外鞘管21的前端。Further, as shown in FIGS. 5 and 6 , the outer sheath moving block 31 is fixed at the rear end of the outer sheath tube 21 , and the rear end of the outer sheath moving block 31 is slidably connected to the first handle 35 .

The outer peripheral wall of the outer sheath joint 24 forms a tooth shape, and the outer sheath tube 21 is sleeved on the outer peripheral wall of the outer sheath joint 24. In this way, assembly of the outer sheath tube 21 and the first handle is facilitated. Preferably, the outer sheath moving block 31 moves backward to abut the first handle and expose the conductive base 14 . In this way, the outer sheath moving block 31 moves backward to abut the first handle and restricts the outer sheath tube 21 from further moving backward, so that the conductive base 14 is completely exposed to the front end of the outer sheath tube 21 .
第一手柄35包括手柄主体以及固定在手柄主体后端的拇指环；第二手柄为双指把手36。方便医生进行单手操作。The first handle 35 includes a handle body and a thumb ring fixed on the rear end of the handle body; the second handle is a two-finger handle 36 . It is convenient for doctors to operate with one hand.
