Description

Technical Field

[0001] The utility model relates to the field of laparoscopic surgical instruments, in particular to a disassembly-assembled electrocoagulation hook. Background Art

[0002] The applicant's prior application (2023211979585) proposed a laparoscopic surgical instrument with a forceps head diameter larger than the operating rod. However, energy instruments such as electrocoagulation hooks are required in laparoscopic surgery, and energy instruments can only enter from the umbilicus, which causes the umbilical wound to increase to 25-40mm. The electrocoagulation hook must be in the same channel as the laparoscope, resulting in a chopstick effect and inconvenient operation. The outer diameter of the traditional laparoscopic electrocoagulation hook is greater than 5mm, and a puncture electrocoagulation hook is required as its channel. The actual skin trauma is more than 7mm, which will definitely leave scars clinically. At present, the length of the electrocoagulation hook below 3mm in clinical practice is only 3mm, and the actual outer diameter of the insulated operating rod of the electrocoagulation hook is too thin, which will bend and deform, making it inconvenient for clinical operation.

DETAILED DESCRIPTION

[0027] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0028] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0029] like Figure 1 and Figure 2 As shown, the electrocoagulation hook structure in this embodiment has a different structure from the traditional electrocoagulation hook. The most important thing is that the traditional electrocoagulation hook structure is modified into a detachable structure. This embodiment only improves the structural features of the electrocoagulation hook and does not elaborate on the electrical performance. The specific structure includes:

[0030] The connecting rod 1 includes an outer rod 1-1 and a conductive rod 1-2 coaxially arranged inside the outer rod 1-1. The outer rod 1-1 is fixedly connected to the handheld portion 5, and the conductive rod 1-2 passes through the handheld portion 5 and is connected to a power source. An insulating layer is filled and arranged between the outer rod 1-1 and the conductive rod 1-2. The outer rod 1-1, the conductive rod 1-2, the handheld portion 5 and the insulating layer are formed in an integral structure, and the surface of the entire connecting rod 1 is not charged.

[0031] One end of the conductive rod 1-2 extends out of the outer rod 1-1, and the extended portion is in a needle tip structure, so that the entire connecting rod 1 can be directly punctured on the abdominal cavity surface through the needle tip.

[0032] The outer surface of the end of the outer rod 1-1 is provided with a threaded section 1-4, which is used for threaded connection with the connecting sleeve 2. In order to prevent the muscle from clamping the tail of the threaded section 1-4 during the puncture of the connecting rod 1, an inclined surface 1-3 is provided between the tail of the threaded section 1-4 and the surface of the outer rod 1-1. The inclined surface 1-3 has a guiding function, which can prevent the muscle from getting stuck and ensure the smooth puncture of the connecting rod 1. The outer surface of the outer rod 1-1 is coated with an insulating layer to achieve complete shielding of the conductive rod 1-2.

[0033] The electric coagulation hook 3 includes an electric hook head 3-1 and an electric hook body 3-2. The electric hook body 3-2 is used to connect with the connecting sleeve 2. The inner side of the electric hook head 3-1 is a working area.

[0034] The connecting sleeve 2 is made of high temperature resistant insulating material, and is provided with internal threads. Both ends of the connecting sleeve 2 are connected, and are respectively used to connect the connecting rod 1 and the electrocoagulation hook 3. The needle tip of the conductive rod 1-2 in the connecting sleeve 2 is inserted into the electric hook body 3-2 of the electrocoagulation hook to realize the electrification of the electrocoagulation hook 3.

[0035] like Figure 5 As shown, in clinical surgery, according to the surgical position, the connecting rod 1 is directly punctured into the abdominal cavity. Then the connecting rod 1 is led out of the abdominal cavity using the laparoscopic surgical channel, and after the electrocoagulation hook 3 and the connecting sleeve 2 are connected to the connecting rod 1, the connecting rod 1 is pulled into the abdominal cavity for surgery. During the whole process, because the connecting rod 1 can be directly punctured, there is no need to open the abdominal cavity additionally, which reduces the damage to the patient and achieves the purpose of minimally invasive surgery.

[0036] In this embodiment, the outer surface of the outer rod 1-1 and the connecting sleeve 2 are both insulators. After the connection is completed, the entire electrocoagulation hook is insulated except for the working area of ​​the electric hook head 3-1, which protects the patient's body from damage during the puncture process and surgery to the greatest extent.

[0037] In this embodiment, in combination with the above, the electrocoagulation hook 3 of different sizes can be replaced according to the actual needs of the operation. The electrocoagulation hook 3 can be a hook-shaped structure or a rod-shaped structure to meet different surgical environments.

[0038] Due to clinical operation reasons, the length of the connecting rod must be guaranteed, and in order to meet the purpose of minimally invasive surgery, an overly long connecting rod will cause uneven force on the connecting rod itself, resulting in inconvenience in operation. Therefore, in this embodiment, a protective sleeve 4 is added to increase the force arm of the connecting rod 1, thereby improving the strength of the connecting rod itself.

[0039] like Figure 3 and Figure 4 As shown, the sleeve 4 is through-connected at both ends. A slotted structure is provided along the axial direction on the side of the sleeve 4. The slotted structure is a through slot 4-1. The through slot 4-1 is connected to the inside of the sleeve 4, so that the connecting rod 1 can be inserted into the sleeve 4 from the through slot 4-1, so that the sleeve 4 is sleeved on the connecting rod 1. One end of the sleeve 4 is connected to the end of the handheld end 5 through a thread, and a locking sleeve 4-2 is provided on the other end of the sleeve 4. The locking sleeve 4-2 is connected to the sleeve 4 through a thread. The locking sleeve 4-2 adopts a split fork structure, and the split fork is used to hold the sleeve 4 and the connecting rod 1. Therefore, the sleeve 4 and the connecting rod 1 form a fixed integrated structure, thereby increasing the force arm of the connecting rod 1 during the operation.

[0040] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
