Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to a guidable bipolar forceps device. Background Art

[0002] At present, more and more open surgeries have been replaced by minimally invasive surgeries. Minimally invasive surgeries have many advantages, such as less surgical trauma, faster postoperative recovery, and beautiful abdominal incision scars. Therefore, minimally invasive surgery is an inevitable trend in the development of surgical methods in the future. In minimally invasive surgeries, there are many situations where human tissue needs to be cut and coagulated, and ablation electrodes are needed at this time. When ablation electrodes are used clinically, they need to enter the human body through a puncture device or other channels to perform electrocoagulation on human tissue.

[0003] There is a kind of guidable bipolar forceps device in the current prior art. Currently, bipolar forceps are used clinically. Some are directly pinched by left and right springs, while others are equipped with guiding devices on the left and right forceps. However, fixing by bonding may cause the risk of falling off, and the practicality is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the bipolar forceps currently used in clinical practice in the prior art are either directly pinched by pinching the left and right spring leaves or equipped with guide devices on the left and right forceps leaves, but there is a risk of falling off by fixing by bonding, and the practicality is poor. A guideable bipolar forceps device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a guidable bipolar tweezers device, comprising a left tweezer blade, a right tweezer blade is provided on one side of the left tweezer blade, a mounting block is commonly installed at one end of the left tweezer blade and the right tweezer blade, a guide column is installed at the end of the left tweezer blade facing the right tweezer blade, and a guide groove block matching the guide column is installed at the end of the right tweezer blade facing the left tweezer blade.

[0006] Preferably, two first pins are installed on one end of the left tweezers blade facing the right tweezers blade, and the guide column is sleeved on the outer sides of the two first pins.

[0007] Preferably, two second pins are installed on one end of the right tweezers blade facing the left tweezers blade, and the guide groove block is sleeved on the outer sides of the two second pins.

[0008] Preferably, a shell is installed on the outer side of the mounting block.

[0009] Preferably, the outer walls of the left tweezers and the right tweezers are provided with an insulating coating.

[0010] Preferably, the guide slot block and the guide column are in the same horizontal plane.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, the first pin and the second pin are respectively embedded in the opposite ends of the left tweezers and the right tweezers, and the guide column and the guide groove block are respectively interference fit on the outside of the first pin and the second pin. The above mutual coordinated assembly plays a guiding role to ensure that the guide device is installed stably without the risk of falling off. By pinching the left and right tweezers, the guide column enters the guide groove block to achieve accurate alignment of the tweezer tips of the left and right tweezers to prevent skew. At the same time, it also effectively controls the rupture of blood vessels due to excessive force and too tight closure of the tweezer tips, and can also avoid damage to other parts during the operation.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Embodiment 1, as Figure 1-3 As shown, the utility model provides a guidable bipolar tweezers device, including a left tweezer blade 1, a right tweezer blade 2 is provided on one side of the left tweezer blade 1, a mounting block 8 is commonly installed at one end of the left tweezer blade 1 and the right tweezer blade 2, a guide column 6 is installed at the end of the left tweezer blade 1 facing the right tweezer blade 2, and a guide groove block 7 matching the guide column 6 is installed at the end of the right tweezer blade 2 facing the left tweezer blade 1.

[0020] The effect achieved by the entire embodiment 1 is that by pinching the left tweezers 1 and the right tweezers 2, the guide column 6 enters the guide groove block 7, so that the tweezer tips of the left tweezers 1 and the right tweezers 2 are accurately aligned to prevent them from tilting. At the same time, it also effectively controls the blood vessels from being broken due to excessive force and the tweezer tips being closed too tightly, and can also avoid damage to other parts during the operation.

[0021] Embodiment 2, as Figure 1-3 As shown, two first pins 4 are installed at the end of the left tweezer 1 facing the right tweezer 2, and the guide column 6 is sleeved on the outside of the two first pins 4. Two second pins 5 are installed at the end of the right tweezer 2 facing the left tweezer 1, and the guide groove block 7 is sleeved on the outside of the two second pins 5. The outer side of the mounting block 8 is installed with a shell 3, the outer walls of the left tweezer 1 and the right tweezer 2 are provided with an insulating coating, and the guide groove block 7 and the guide column 6 are in the same horizontal plane.

[0022] The effect achieved by the entire embodiment 2 is that, through the setting of the first pin 4 and the second pin 5, the guide column 6 and the guide groove block 7 are stably installed on the left tweezer blade 1 and the right tweezer blade 2, so that they are stably installed, avoiding the phenomenon of looseness of the traditional bonding type, and being more practical. This device sprays an insulating coating on the left tweezer blade 1 and the right tweezer blade 2 after the first pin 4 and the second pin 5 are covered with protective caps. Through the setting of the mounting block 8 and the shell 3, the left tweezer blade 1 and the right tweezer blade 2 can be installed.

[0023] Working principle: When the device is used, the left tweezers 1 and the right tweezers 2 are first installed through the setting of the mounting block 8 and the shell 3. After the installation, the left tweezers 1 and the right tweezers 2 are pinched to make the guide column 6 enter the guide groove block 7, so that the tweezer tips of the left tweezers 1 and the right tweezers 2 are accurately aligned to prevent skewness. At the same time, it also effectively controls the rupture of blood vessels due to excessive force and too tight closure of the tweezer tips. It can also avoid damage to other parts during operation, ensuring that the guide device is installed stably without the risk of falling off.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
