Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of abdominal single-hole puncture instruments, in particular to an abdominal puncture instrument with electric knife power. Background Art
[0002] A laparoscopic trocar is a disposable medical device suitable for the delivery of gas in minimally invasive surgery and the creation of a channel for endoscopes and surgical instruments to enter and exit the body cavity from the outside. Existing trocars usually use the threads of the trocar sheath wall itself to increase the friction with the skin to fix the trocar, thereby ensuring the normal progress of the operation.
[0003] When in use, the inner end of the trocar usually needs to penetrate deep into the patient's body, thereby forming a channel on the patient's body that is convenient for subsequent surgical equipment such as laparoscopes to enter. When the laparoscope is inserted into the patient's body, it may be blocked by tissues or other small pieces of flesh in the patient's body, resulting in the laparoscope being unable to operate safely in the patient's body. The laparoscope itself is limited in size and lacks the means to handle these tissues or small pieces of flesh, which will directly affect the progress of abdominal surgery. In view of this, we propose an abdominal trocar with electrosurgical power. Utility Model Content
[0004] The purpose of the utility model is to provide a abdominal puncture device with electric knife power to solve the problems raised in the above background technology.
[0005] To achieve the above object, the utility model provides the following technical solution: a abdominal puncture device with electric knife power, comprising a holding seat, a sheath is fixedly mounted on the side wall of the holding seat, an electric knife assembly is arranged inside the sheath, and the electric knife assembly comprises:
[0006] An inner cavity is provided inside the sheath tube, an inner tube is movably installed inside the inner cavity, a handle is fixedly installed at the end of the inner tube, and an end of the handle away from the inner tube is fixedly connected to an external wire;
[0007] A groove is provided on the arc-shaped outer wall of the inner tube, a conductive strip is provided inside the groove, and a blade is provided at one end of the conductive strip away from the handle.
[0008] Preferably, the outer diameter of the inner cavity is matched with the outer diameter of the inner tube, and a circular hole matching the size of the inner cavity is provided inside the holding seat, so that a hollow passage is formed between the holding seat and the inside of the sheath tube.
[0009] Preferably, the width of the conductive strip is matched to the width of the groove, and the thickness of the conductive strip is smaller than the depth of the groove, so that the inner tube will not interfere with the movement of the inner tube when it moves forward and backward in the inner cavity.
[0010] Preferably, an insulating layer is provided on the outer surface of the conductive strip away from the center of the inner tube to prevent the conductive strip from discharging itself and affecting the safe use of the equipment.
[0011] Preferably, the thickness of the blade is greater than the depth of the groove, so that the blade at the front end of the inner tube is exposed from the outer surface of the inner tube, so that it can cut tissue in the patient's body after being powered on.
[0012] Preferably, the inner tube is made of a transparent material, the interior of the inner tube is hollow, and a laparoscope is movably provided on the inner tube.
[0013] Compared with the prior art, the utility model provides a abdominal puncture device with electric knife power, which has the following beneficial effects:
[0014] 1. The abdominal puncture device with electric knife power is provided with an electric knife assembly, so that medical staff can control the depth of the inner tube into the patient's abdominal cavity by holding the handle, or perform outer shell operations between the layers of the abdominal wall, so as to accurately control the operation position in the patient's body under direct vision of the laparoscope, avoid causing harm to the patient's body, and cooperate with the blade at the end of the inner tube to cut and separate the patient's abdominal wall layers and tissues, so as to facilitate abdominal surgery. At the same time, because the inner tube has a certain length, it is more convenient and safe for medical staff to operate.
[0015] 2. The abdominal puncture device with electric knife power has three groups of conductive strips and blades on the outside of the inner tube, so that the blade at the end of the inner tube has a better cutting effect on the patient's abdominal wall layers and tissues. Combined with the inner tube made of transparent material and the laparoscope movably arranged in the inner tube, the efficiency and safety of abdominal surgery operations by medical staff are greatly improved.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a abdominal puncture device with electric knife power, including a holding seat 1, a sheath 2 is fixedly installed on the side wall of the holding seat 1, an electric knife assembly 3 is arranged inside the sheath 2, and the electric knife assembly 3 includes an inner cavity 31, an inner tube 32, a handle 33, an external wire 34, a groove 35, a conductive strip 36 and a blade 37.
[0023] In one embodiment of the utility model, an inner cavity 31 is opened inside the sheath tube 2, an inner tube 32 is movably installed inside the inner cavity 31, a handle 33 is fixedly installed at the end of the inner tube 32, an end of the handle 33 away from the inner tube 32 is fixedly connected to an external wire 34, a groove 35 is opened on the arc-shaped outer wall of the inner tube 32, a conductive strip 36 is arranged inside the groove 35, and a blade 37 is arranged at the end of the conductive strip 36 away from the handle 33.
[0024] Furthermore, a slope is provided at one end of the sheath tube 2 away from the holding seat 1, so that it is convenient for medical personnel to hold the holding seat 1 and insert the sheath tube 2 into the patient's abdominal cavity along the surgical incision previously opened on the patient's abdominal cavity, while reducing the obstruction encountered during the process of continuously penetrating into the patient's abdominal cavity. In addition, a control button is provided on the outer side of the holding seat 1 to assist medical personnel in performing surgical operations.
[0025] In addition, the outer diameter of the inner cavity 31 is adapted to the outer diameter of the inner tube 32, and a circular hole adapted to the size of the inner cavity 31 is opened inside the holding seat 1, so that the holding seat 1 and the inside of the sheath tube 2 have a hollow passage, which is convenient for medical staff to use laparoscopes 4 and other medical equipment to examine and perform surgery on patients. At the same time, the inner tube 32 can slide freely in the inner cavity 31. Specifically, a plug is provided at the end of the external wire 34 away from the handle 33, so that it is connected to an external power supply device to power the conductive strip 36. Furthermore, a button is provided on the top of the handle 33 to facilitate medical staff to control whether the conductive strip 36 is energized while holding it. Specifically, a circuit controller is provided inside the handle 33, and the external wire 34 and the conductive strip 36 have a circuit in series with the button inside the handle 33, so that the button can control the power on and off of the circuit.
[0026] In the embodiment of the utility model, the width of the conductive strip 36 is adapted to the width of the groove 35, and the thickness of the conductive strip 36 is less than the depth of the groove 35, so that the inner tube 32 will not interfere with the movement of the inner tube 32 when it moves forward and backward in the inner cavity 31. At the same time, an insulating layer is provided on the outer surface of the conductive strip 36 away from the center of the inner tube 32 to prevent the conductive strip 36 from discharging and affecting the safe use of the device, and also to avoid causing harm to the patient. In addition, the thickness of the blade 37 is greater than the depth of the groove 35, so that the blade 37 at the front of the inner tube 32 is not too thick. The blade 37 at the end position exposes the outer surface of the inner tube 32, so that when the inner tube 32 penetrates into the patient's abdominal cavity, the conductive strip 36 is energized by the control of the handle 33, and finally the blade 37 generates high-frequency vibration and heat to cut the abdominal wall layers or tissues of the patient's body. The inner tube 32 is made of transparent material, and the interior of the inner tube 32 is hollow. The inner tube 32 is movably provided with a laparoscope 4, so that the front blade 37 can be observed and micro-manipulated in time through the laparoscope 4 when performing cutting operations in the patient's body, which is convenient for medical staff to operate.
