Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of finger force device, more particularly to a laparoscope handle grip strength trainer. BACKGROUND

[0002] Laparoscopic surgery requires surgeons to hold surgical tools for a long time, and the hand muscle strength, finger flexibility and coordination are required to be higher. In this scenario, the surgeon needs to maintain the same posture for a long time, so it is necessary to have enough single finger strength and combined strength. If the action is deformed or the clamped tissue falls off due to insufficient strength, it will affect the operation.

[0003] The existing grip strength trainers are mostly used for hand exercise in the fields of fitness and musical instruments, and these two types of training devices do not pay attention to the force exertion at specific holding angles. The existing surgical simulation devices mostly adopt a scissor-shaped holding structure, and focus on surgical actions such as stretching and turning, but ignore the training of single finger force and combined force.

[0004] There is a lack of special design for the handle holding characteristics in the scenario of laparoscopic surgery. Therefore, it is necessary to develop a laparoscopic surgery handle grip strength trainer to simulate the holding method of laparoscopic surgical instruments such as curved forceps and scissors, and to train the single finger force and combined force at specific holding angles in this scenario through adjustable grip strength and holding posture, so as to improve the hand strength, finger flexibility and coordination of surgeons, thereby improving the operation stability and improving the surgical effect. SUMMARY

[0005] The utility model aims at overcoming at least one of the above-mentioned deficiencies of the prior art, and provides a laparoscope handle grip strength trainer for training the single finger force and combined force at specific holding angles in the scenario of laparoscopic surgery, so as to improve the hand strength, finger flexibility and coordination of laparoscopic operators, thereby improving the operation stability and improving the surgical effect.

[0037] The four-finger pliers handle 200 is provided with a ring finger ring 210, and the four-finger pliers handle 200 is fixedly connected to the probe rod 100;

[0038] The thumb pliers handle 300 is provided with a thumb ring 310, and the thumb pliers handle 300 is movably connected to the four-finger pliers handle 200;

[0039] A first finger strength device 400 is fixed within the thumb ring 310 and the ring finger ring 210; and

[0040] The second finger forceper 500 is slidably connected to the four-finger pliers handle 200 and is located outside the ring finger ring 210.

[0041] In the above scheme, the combination of the probe rod 100 and the thumb forceps handle 300 and the four-finger forceps handle 200 simulates the shape of the laparoscope handle, the thumb ring 310 and the ring finger ring 210 simulate the scissors finger ring of the laparoscope handle; in combination with the plurality of finger force devices inside and outside the finger ring, the simulation exercise of the user holding while exerting force on a single finger and combined force is realized, which helps to enhance the hand strength of the laparoscope operator.

[0042] The laparoscope handle grip strength trainer further comprises a double-axis joint 120, a universal ball joint 130 and a suction cup 140, the end of the probe rod 100 away from the four-finger forceps handle 200 is connected to the suction cup 140 through the universal ball joint 130, and the probe rod 100 is divided into multiple sections and connected to each other through the double-axis joint 120. In actual laparoscopic operation, the distal end of the probe rod 100 is limited, but the angle of the probe rod 100 also has a certain adjustable range. Therefore, the suction cup 140 is provided for limiting the position of the distal end of the probe rod of the grip strength trainer, and the universal ball joint 130 is provided to help the user adjust the holding angle, thereby simulating the holding force at different angles. The double-axis joint 120 is provided to further improve the adjustment range of the angle of the probe rod 100, making the simulation operation more flexible.

[0043] A knob 110 is provided on the probe rod. The existing laparoscope handle is provided with a knob, which is convenient for the user to hold with the index finger, thereby adjusting the clamping direction of the front end of the probe rod. The laparoscope handle grip strength trainer is provided with the knob 110, which is convenient for the user to simulate the index finger leaning while practicing the holding force.

[0044] A display screen 600 is provided on the probe rod 100 and is electrically connected to the first finger force device 400 and the second finger force device 500. The display screen 600 is provided to display the number of finger pressure and the force, which is convenient for the user to monitor the intensity of the simulation exercise.

[0045] As shown in Fig. 2 The second finger force device 500 comprises:

[0047] A pressing plate 520 is snap-fit connected to the top of the movable sleeve 510; and

[0048] A support plate 530 is provided at the inner side of the lower end of the movable sleeve 510 and is connected to the bottom of the pressing plate 520 through a spring.

[0049] Different users have different finger sizes, and there are various holding methods, such as using the index finger to participate in the holding of the four-fingered clamp 200, or placing the index finger on the probe rod 100, so the grip strength trainer needs to adapt to different finger spacings. The bottom of the movable sleeve 510 is in sliding connection with the four-fingered clamp 200, so that the second finger force device 500 can freely slide on the four-fingered clamp 200, thereby facilitating the user to adjust the finger spacing independently and improving the holding comfort.

[0050] The difference between the first finger force device 400 and the second finger force device 500 is that the bottom of the first finger force device 400 is fixedly connected with the finger ring instead of being in sliding connection.
