Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a detection mechanism for a loading assembly of an electric surgical instrument. Background Art

[0002] There is an existing electric surgical instrument that needs to be assembled with a gun body before use and then fired. However, before the external device is assembled and inserted, the gun body is in a normal operating state, which can easily cause the internal structure of the gun body to move, resulting in the external device being unable to be inserted and matched, and the normal use of the instrument cannot be guaranteed.

[0003] In view of this, it is necessary to improve the existing instrument technology to ensure the smooth insertion of external devices, ensure the connection of the instrument's electrical system, and ensure the normal progress of the operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a detection mechanism for a loading assembly of an electric surgical instrument to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: an electric surgical instrument loading component detection mechanism, including a transmission device, a safety steering block, a safety spring, and a circuit system connection button. The safety steering block, the safety spring, and the circuit system connection button are on the surgical instrument gun body. The safety steering block is in contact with the safety spring. The safety steering block is extended to the side away from the circuit system connection button under the pressure of the safety spring. The transmission device includes a transmission connecting rod, a transmission protective sleeve and a transmission core shaft. The transmission core shaft is arranged in the transmission protective sleeve. One end of the transmission connecting rod is fixed to the end of the transmission protective sleeve away from the external device, and the other end of the transmission connecting rod is in contact with the safety steering block. The thrust of the transmission connecting rod causes the safety steering block to rotate and press the circuit system connection button, thereby controlling the surgical instrument circuit system to ensure the normal progress of subsequent operations. The transmission core shaft, the transmission protective sleeve and the transmission connecting rod are in contact in sequence. The present invention controls the retreat and advancement of the transmission device by inserting and removing the external device, thereby controlling the connection and disconnection of the circuit system.

[0006] As a preferred embodiment, the safety spring is installed on the surgical instrument gun body through a fixed shaft, one end of the safety spring is fixed on the surgical instrument gun body, and the other end is arranged on the safety steering block. Under the action of the spring, the safety steering block is extended to the side away from the circuit system connection button. When in use, one end of the transmission connecting rod is in contact with the safety steering block during operation to control the rotation of the safety steering block, thereby controlling the circuit system connection button. When the external device is not inserted, the safety steering block is in a depressed state, and the circuit system connection button pops out.

[0007] As a preferred embodiment, the circuit system on button is fixed on a fixing plate arranged on the surgical instrument gun body.

[0008] As a preferred embodiment, the transmission protective sleeve is provided with a center hole, and the transmission core shaft is slidably disposed in the center hole of the transmission protective sleeve.

[0009] As a preferred embodiment, a slide groove is provided on the transmission connecting rod, and a protrusion cooperating with the slide groove is provided on the safety steering block, and the safety steering block moves in the direction of the circuit system connection button through the cooperation between the slide groove and the protrusion. The beneficial effects of the present invention are as follows: compared with the prior art, the present invention prevents the misoperation of the gun body before the external device is inserted into the gun body, which causes the problem of the external device insertion and matching, and ensures the normal operation of the operation.

[0022] The present invention is further described in conjunction with the accompanying drawings so that those skilled in the art can better implement the present invention.

[0023] The embodiment of the present invention is an electric surgical instrument loading component detection mechanism, including a transmission device, a safety steering block 3-1, a safety spring 3-2, and a circuit system connection button 3-4. The safety steering block 3-1, the safety spring 3-2, and the circuit system connection button 3-4 are on the surgical instrument gun body 3, the safety steering block 3-1 is in contact with the safety spring 3-2, and the safety steering block 3-1 is extended to a side away from the circuit system connection button 3-4 by the pressure of the safety spring 3-2. The transmission device includes a transmission connecting rod 3-3, a transmission protective sleeve 3-8 and a transmission spindle 3-7. The transmission spindle 3-7 is arranged on the transmission In the protective cover 3-8, one end of the transmission connecting rod 3-3 is fixed to the end of the transmission protective cover 3-8 away from the external device 1, and the other end of the transmission connecting rod 3-3 is in contact with the safety steering block 3-1. The thrust of the transmission connecting rod 3-3 causes the safety steering block 3-1 to rotate and press the circuit system connection button 3-4, thereby controlling the surgical instrument circuit system to ensure the normal progress of subsequent operations. The transmission core shaft 3-7, the transmission protective cover 3-8 and the transmission connecting rod 3-3 are in contact in sequence. The present invention controls the retreat and advancement of the transmission device by inserting and removing the external device 1, thereby controlling the connection and disconnection of the circuit system.

[0024] The safety spring 3-2 of the embodiment of the present invention is installed on the surgical instrument gun body 3 through a fixed shaft, one end of which is fixed on the surgical instrument gun body 3, and the other end is arranged on the safety steering block 3-1. The safety steering block 3-1 is extended to the side away from the circuit system connection button 3-4 by the action of the spring. When in use, one end of the transmission connecting rod 3-3 is in contact with the safety steering block 3-1 during operation to control the rotation of the safety steering block 3-1, thereby controlling the circuit system connection button 3-4. When the external device 1 is not inserted, the safety steering block 3-1 is in a depressed state, and the circuit system connection button 3-4 pops out. The circuit system connection button 3-4 is fixed on the fixed plate 3-5 arranged on the surgical instrument gun body 3. The transmission protective cover 3-8 is provided with a center hole, and the transmission spindle 3-7 is slidably arranged in the center hole of the transmission protective cover 3-8. The transmission connecting rod 3-3 is provided with a slide groove, and the safety steering block 3-1 is provided with a protrusion that cooperates with the slide groove. The safety steering block 3-1 moves toward the direction of the circuit system connection button 3-4 through the cooperation between the slide groove and the protrusion.

[0025] like Figure 1 As shown, the surgical instrument includes an external device 1 and a gun body 3. Before the operation, the staff assembles the external device 1 and the gun body 3, and then extends the external device 1 into the patient's body. Figure 2 As shown, when the external device 1 is assembled, the incorrect operation of the gun body 3 causes the hinge connecting rod 2 to extend outward too long or too short, resulting in the external device 1 and the gun body 3 not being able to fit together, which is not conducive to the normal operation.

[0026] like Figure 3 and Figure 4As shown, when the external device 1 and the gun body 3 are not assembled, that is, the transmission device is not subjected to pressure from the direction of the gun body 3, the safety steering block 3-1 is in the original state, and the safety steering block 3-1 is pressed down by the pressure of the safety spring 3-2 and separated from the circuit system connection button 3-4. In this way, the instrument circuit system is in a disconnected state, and the operation of the gun body 3 is invalid, which prevents the gun body 3 from being misoperated before assembly, resulting in matching problems.

[0027] like Figure 4 and Figure 5 As shown, when the external device 1 and the gun body 3 are assembled, the safety steering block 3-1 is subjected to pressure, which pushes the safety steering block 3-1 to rotate, presses the circuit system connection button 3-4, connects the instrument electric system, presses the instrument switch, and completes normal operation.

[0028] like Figure 7 As shown, when the instrument is normally assembled, the transmission spindle 3-7 is compressed, driving the transmission protection cover 3-8 and the transmission connecting rod 3-3 to be compressed, the safety steering block 3-1 presses the circuit system connection button 3-4, the instrument circuit system is connected, and the instrument can operate normally.

[0029] like Figure 8 , Fig. 9 The figure shows the connection state between the transmission protective sleeve 3-8 and the transmission connecting rod 3-3, and the transmission spindle 3-7 and the transmission protective sleeve 3-8.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
