Description

Technical Field

[0001] The present invention relates to the field of medical device detection, and specifically to a hemostatic forceps detection device. Background Art

[0002] A hemostatic forceps is a surgical instrument that achieves blood blockage by clamping blood vessels. After the hemostatic forceps clamps the blood vessels, it is locked through a lock. Therefore, the locking effect of the lock affects whether the hemostatic forceps can normally clamp the blood vessels to play a hemostatic role. During the operation, after the hemostatic forceps clamps the blood vessels, it may swing due to the progress of the operation. When the hemostatic forceps swings, the lock may become disengaged, thus affecting the normal hemostatic function of the hemostatic forceps. Therefore, before the hemostatic forceps is put into normal use, it is necessary to detect the locking effect of its lock. Summary of the Invention

[0003] The purpose of the present invention is to provide a hemostatic forceps detection device to overcome the above-mentioned defects in the prior art.

[0004] According to a hemostatic forceps detection device of the present invention, it includes a base. A vibration table for placing the hemostatic forceps is arranged on the upper side of the base. Two support rods are fixed on the base. One end of the vibration table is rotatably connected between the two support rods. A support plate is arranged between the vibration table and the base. A compression spring is fixed between the support plate and the vibration table, and the compression spring is located at the other end of the vibration table. Two vertically symmetric air pipes are arranged between the two support rods. A rubber tube communicating with the two air pipes is detachably connected between the two air pipes. The hemostatic forceps clip can be clamped on the rubber tube. A motor is fixedly connected to the lower end face of the support plate, and an eccentric wheel is fixed on the rotating shaft of the motor.

[0005] Through the above technical solution, the hemostatic forceps is clamped on the rubber tube. The motor drives the eccentric wheel to rotate, causing the vibration table to swing up and down, so that the hemostatic forceps continuously swings on the vibration table, thereby detecting whether the hemostatic forceps will become loose due to shaking after being clamped. If it becomes loose, the hemostatic forceps will slide out of the vibration table along its surface to the side away from the support rod under the swing of the vibration table.

[0006] Further, a groove is formed on the side edge of the vibration table close to the rubber tube and recessed away from the rubber tube. The rubber tube penetrates through the groove. Two guard plates are fixed on the upper end face of the vibration table and located on both side edges thereof. The guard plates are located on both sides of the rubber tube.

[0007] Through the above technical solution, the setting of the guard plates is beneficial to restricting the hemostatic forceps on the vibration table during the swing of the vibration table.

[0008] Further, fixing rings are fixed on the outer peripheries of the two air pipes, and connecting rods are fixed between the outer peripheries of the fixing rings and the two support rods on both sides.

[0009] Through the above technical solution, the connecting rod and the fixing ring fix the ventilation pipe between the two support rods, so that the two ventilation pipes remain stable during the swinging process of the hemostatic forceps.

[0010] Further, two fixing rods are fixed on the upper end surface of the base. The two fixing rods are arranged close to the compression spring. The support plate is fixed on the two support rods and the fixing rods and is horizontally arranged.

[0011] Through the above technical solution, the support plate is fixed on the fixing rods and the support rods, so that the support plate remains stable during the swinging process of the vibrating table, and further enables the support plate to stably support the compression spring.

[0012] Further, connecting pipes are arranged at both the upper and lower ends of the rubber tube. On the end face of the connecting pipe close to the rubber tube, a sleeve pipe extending into the rubber tube is fixedly provided. The rubber tube is sleeved on the sleeve pipe and fixedly connected to the outer periphery of the sleeve pipe. The diameter of the connecting pipe is larger than that of the sleeve pipe, and a step is formed at the connection between the two. A sealing ring fixed on the step is arranged at the end of the connecting pipe close to the rubber tube. A rotating ring is rotatably connected to the end of the connecting pipe away from the rubber tube. A vertically arranged vertical groove and a horizontally arranged horizontal groove are formed on the rotating ring. An "L" shape is formed between the vertical groove and the horizontal groove. The upper end of the vertical groove is open. A pin that can penetrate through the vertical groove and be stuck into the horizontal groove is fixedly provided on the outer periphery of the ventilation pipe.

[0013] Through the above technical solution, by rotating the rotating ring, the sleeve pipe can be slid along the vertical groove and the horizontal groove and be stuck into the horizontal groove, so as to realize the detachable connection between the ventilation pipe and the rubber tube, and thus facilitate the replacement of the rubber tube.

[0014] Further, a piston cylinder communicated with it is fixed at the lower end of the lower ventilation pipe. A piston is slidably connected in the piston cylinder. A tension spring is fixed between the upper end face of the piston and the upper side wall in the piston cylinder. The lower end of the piston cylinder is open. The lower end of the piston cylinder is fixed on the upper end face of the base. A contact switch located below the piston is fixed in the upper end face of the base. An air injection pipe communicated with it is fixedly provided on the outer periphery of the lower ventilation pipe. The other end of the air injection pipe is connected to an air pump. The contact switch is electrically connected to the air pump. A one-way valve is fixed in the air injection pipe.

[0015] Through the above technical solution, the air pump inflates the lower ventilation pipe through the air injection pipe. After the rubber tube is clamped by the hemostatic forceps, air is injected into the piston cylinder, so that the piston moves downward until it touches the contact switch, and then the air pump can be controlled to stop inflating. At this time, the clamped part of the rubber tube expands under the action of the gas, so as to simulate the effect of the blood vessel being clamped.

[0016] Furthermore, a fixing frame is fixed to the lower end face of the air pump, and the lower end of the fixing frame is fixed to the upper end face of the base.

[0017] Through the above technical solution, the setting of the fixing frame is beneficial to the installation of the air pump.

[0018] The beneficial effect of the present invention is that the hemostatic forceps are clamped on the rubber tube. The eccentric wheel is driven to rotate by the motor, so that the vibrating table swings up and down, thereby making the hemostatic forceps continuously swing on the vibrating table, so as to detect whether the hemostatic forceps will become loose due to shaking after being clamped. If loosening occurs, the hemostatic forceps will slide out of the vibrating table along its surface to the side away from the support rod under the swing of the vibrating table, which is convenient for collecting the hemostatic forceps with low quality.

[0022] In order to make the purpose and advantages of the present invention more clear and understandable, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "up and down" and "left and right" do not limit their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent. The specific features of a hemostatic forceps detection device will be described in detail below: An embodiment of the present invention: Referring to Figures 1-7 , the present invention provides a hemostatic forceps detection device, including a base 10. A vibrating table 20 for placing the hemostatic forceps is arranged on the upper side of the base 10. Two support rods 12 are fixed on the base 10. One end of the vibrating table 20 is rotatably connected between the two support rods 12. A support plate 30 is arranged between the vibrating table 20 and the base 10. A compression spring 31 is fixed between the support plate 30 and the vibrating table 20. The compression spring 31 is located at the other end of the vibrating table 20. Two symmetrically arranged air pipes 60 are arranged between the two support rods 12. A rubber tube 50 communicating with the two air pipes 60 is detachably connected between the two air pipes 60. The hemostatic forceps clip can be clamped on the rubber tube 50. A motor 33 is fixedly connected to the lower end surface of the support plate 30. An eccentric wheel 32 is fixed on the rotating shaft of the motor 33.

[0023] Referring to Figure 1 , a groove is formed by the side edge of the vibrating table 20 close to the rubber tube 50 recessing away from the rubber tube 50. The rubber tube 50 penetrates through the groove. Two guard plates 21 are fixed on the upper end surface of the vibrating table 20 and are located on both sides of the rubber tube 50.

[0024] Referring to Figure 1 , Figure 3 , fixing rings 17 are fixed on the outer peripheries of the two air pipes 60. Connecting rods 16 are fixed between the outer peripheries of the fixing rings 17 and the two support rods 12 on both sides.

[0025] Referring to Figure 1 , two fixing rods 11 are fixed on the upper end surface of the base 10. The two fixing rods 11 are arranged close to the compression spring 31. The support plate 30 is fixed on the two support rods 12 and the fixing rods 11 and is horizontally arranged.

[0026] Referring to Figure 3 , Figure 6 , Figure 7, connecting pipes 54 are provided at both the upper and lower ends of the rubber tube 50. Sleeve pipes 51 extending into the rubber tube 50 are fixedly provided on the end faces of the connecting pipes 54 close to the rubber tube 50. The rubber tube 50 is sleeved on the sleeve pipes 51 and fixedly connected to the outer periphery of the sleeve pipes 51. The diameter of the connecting pipe 54 is larger than that of the sleeve pipe 51, and a step is formed at the connection between the two. A sealing ring 52 fixed on the step is provided at one end of the connecting pipe 54 close to the rubber tube 50. A rotating ring 53 is rotatably connected to the end of the connecting pipe 54 far from the rubber tube 50. A circular ring is formed by the extension of the end face of the rotating ring 53 close to the rubber tube 50 into the connecting pipe 54. An annular protrusion is fixedly provided on the outer periphery of the circular ring and is embedded in the inner peripheral wall of the connecting pipe 54 and rotates therein, so that one end of the rotating ring 53 close to the rubber tube 50 can be restricted within the connecting pipe 54. A vertically arranged vertical groove 531 and a horizontally arranged horizontal groove 532 are provided on the rotating ring 53. An "L" shape is formed between the vertical groove 531 and the horizontal groove 532. The upper end of the vertical groove 531 is open. A pin 61 that can penetrate the vertical groove 531 and be stuck into the horizontal groove 532 is fixedly provided on the outer periphery of the ventilation pipe 60. When the pin 61 is stuck into the horizontal groove 532, the end of the ventilation pipe 60 close to the rubber tube 50 is in close contact with the sealing ring 52.

[0027] Refer to Figure 2 , Figure 5 , a piston cylinder 40 communicated with it is fixed at the lower end of the lower ventilation pipe 60. A piston 42 is slidably connected in the piston cylinder 40. A tension spring 41 is fixed between the upper end face of the piston 42 and the upper side wall inside the piston cylinder 40. The lower end of the piston cylinder 40 is open, and the lower end of the piston cylinder 40 is fixed on the upper end face of the base 10. A contact switch 43 located below the piston 42 is fixed inside the upper end face of the base 10. An air injection pipe 70 communicated with it is fixedly provided on the outer periphery of the lower ventilation pipe 60. The other end of the air injection pipe 70 is connected to the air pump 14. The contact switch 43 is electrically connected to the air pump 14. A one-way valve 71 is fixed in the air injection pipe 70. The air in the air injection pipe 70 can only be injected into the lower ventilation pipe 60 through the one-way valve 71, and the gas in the ventilation pipe 60 cannot be injected into the air injection pipe 70 through the one-way valve 71. When the contact switch 43 is squeezed by the piston 42, the contact switch 43 is triggered, and the air pump 14 is controlled to close through a wire. When the contact switch 43 is not squeezed, the contact switch 43 controls the air pump 14 to restart through a wire.

[0028] Refer to Figure 1 , Figure 2 , a fixing frame 15 is fixed on the lower end face of the air pump 14, and the lower end of the fixing frame 15 is fixed on the upper end face of the base 10.

[0029] When it is necessary to detect the hemostatic forceps, the air pump 14 is started, so that air is injected into the lower ventilation pipe 60 through the air injection pipe 70, and the air in the lower ventilation pipe 60 passes through the rubber tube 50 and is discharged from the upper ventilation pipe 60.

[0030] When detecting the hemostatic forceps, hold the rubber tube 50 with the hemostatic forceps and place the hemostatic forceps on the vibrating table 20. At this time, the air in the lower air pipe 60 is injected downward into the piston cylinder 40, so that the piston 42 moves downward against the tension of the tension spring 41 until it touches the contact switch 43, thereby closing the air pump 14 and stopping injecting air into the lower air pipe 60.

[0031] At this time, start the motor 33 to make the eccentric wheel 32 rotate. Since the center of gravity of the eccentric wheel 32 deviates from the rotation axis of the motor 33, the vibrating table 20 vibrates, and thus the hemostatic forceps swing with the vibration of the vibrating table 20. If the locking effect of the lock of the hemostatic forceps is good, the lock remains locked during the swinging process of the hemostatic forceps, and thus the hemostatic forceps always clamp the rubber tube 50. Then the air in the piston cylinder 40 is still stored in the piston cylinder 40, and the piston 42 remains in contact with the contact switch 43. After a period of time, it can be confirmed that the locking effect of the lock of the hemostatic forceps is good, and then the hemostatic forceps can be removed from the vibrating table 20, and the hemostatic forceps are separated from the rubber tube 50.

[0032] After the hemostatic forceps are separated from the rubber tube 50, the air in the piston cylinder 40 is discharged through the lower air pipe 60, the rubber tube 50 and the upper air pipe 60. The piston 42 is separated from the contact switch 43, and then the air pump 14 restarts. Clamp the next hemostatic forceps to be detected on the rubber tube 50. If the locking effect of the lock of the newly detected hemostatic forceps is poor, the locks will disengage from each other during the swinging process of the new hemostatic forceps with the vibrating table 20, and then the jaws of the hemostatic forceps will be separated from the rubber tube 50. During the continuous swinging of the vibrating table 20, the hemostatic forceps slide out along the surface of the vibrating table 20 in a direction away from the rubber tube 50, and the rubber tube 50 returns to the ventilated state.

[0033] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
