Medical screws are commonly used for fixing bones, and once the bone of a wounded is damaged, the screw can be matched with a connecting plate to be used for connecting and fixing the bone, so that recovery of the wounded is facilitated. Whereas screw extraction devices for extracting screws are commonly used in surgery, doctors separate screws from bone by means of the screw extraction device. The screw implanted in the bone needs to be fixed by a special fixing device during the taking-out process of the doctor, but the taking-out process of the screw is very difficult, and the screw needs to be taken out of the bone by means of the screw taking-out device because the connection between the screw and the bone is very stable. On the other hand, screws also require the aid of special tools during the implantation into bone.

However, in the use process of the traditional nail taking device, particularly when the screw is in a state of being taken out from a bone, the screw needs to be acted by an electric drill to separate the screw from the joint of the bone, but a lot of iron skips are generated in the process of the screw being driven by the electric drill, a doctor needs to wash the electric drill and the screw during working by a washing device, and thus extra personnel need to be configured for operation in the operation process, the operation quality is affected, the manpower is wasted, and the patient is greatly painful from the aspect of the body and the spirit; certain impurities are also generated during the process of implanting the screw into the bone, and the impurities also need to be washed in time.

The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

A gripping apparatus for medical fields, through which a professional user such as a doctor or nurse can improve the operation accuracy and the effectiveness of a nail taking process, as shown in fig. 1 to 7B. The clamping device is used in a screw extraction procedure in which a screw is used for bone attachment, but in which the screw is not easily removed by a screw extractor, and therefore requires the use of a drill for handling the screw. However, in the conventional technology, if a user directly manipulates the drill bit to process the screw, there is a disadvantage in that, on one hand, the drill bit is directly aligned to the screw to perform work, the drill bit is easily deviated due to the change of stress during the work, and thus the situation easily causes operation risk. On the other hand, when the drill bit is used for processing the screw, iron cutting impurities are generated, and if the impurities are not processed in time, the impurities easily enter the human body, and the health of the human body is affected.

The clamping device of the present invention can effectively overcome the above-mentioned drawbacks, and specifically, the clamping device includes a fixing device 10 and a positioning device 20, the positioning device 20 is disposed on the fixing device 10 in a matching manner, and further, the fixing device 10 is clamped on a steel plate, and the positioning device 20 is disposed right above the screw, so that a user can use a drill to process the screw.

It should be noted that the fixing device 10 includes an operating component 11 and a clamping component 12, the clamping component 12 integrally extends to the operating component 11, and a user controls the clamping component 12 to act on the steel plate by operating the operating component 11. In other words, the state of the clamping assembly 12 can be operated by the operating assembly 11 so that the clamping assembly 12 can clamp the steel plate. The opening of the clamping assembly 12 is adjusted according to the size of the steel plate to be clamped, the operating assembly 11 controls the opening of the clamping assembly 12 and provides an acting force to the clamping assembly 12, so that the clamping assembly 12 acts on the steel plate to form a clamping effect on the steel plate, and a stable setting state provided by the positioning device 20 arranged on the clamping assembly 12 is convenient for a user to operate. Preferably, the change of the state of the clamping assembly 12 and the change of the state of the operating assembly 11 are synchronized and related such that, on the one hand, the state of the clamping assembly 12 can be adjusted by controlling the state of the operating assembly 11 and, on the other hand, the state of the clamping assembly 12 can be adjusted to a desired state with precision by controlling the operating assembly 11, for example, the opening of the clamping assembly 12 can be adjusted to a desired size with precision by the operating assembly 11, so that the gripping device is used.

It should be noted that the operating component 11 and the clamping component 12 form a certain inclination angle, so that the fixing device 10 is convenient for a user to hold and operate. Due to the structural design of the inclination angle, the holding and force application of the fixing device 10 are more convenient for a user to fix the steel plate. It will be appreciated that the user operates the fixture 10 in a manner to hold the operating assembly 11.

Further, the operating assembly 11 includes a first operating lever 111 and a second operating lever 112, the first operating lever 111 is pivotally connected to the second operating lever 112, the first operating lever 111 and the second operating lever 112 have an X-shape, and a relative movement between the first operating lever 111 and the second operating lever 112. It should be noted that, as understood by those skilled in the art, due to the moment problem, the shaft connection position between the first lever 111 and the second lever 112 is close to the front end of the two levers, so that the user can conveniently apply force to the first lever 111 and the second lever 112 to reduce the force applied by the operating assembly 11 to the clamping assembly 12.

Further, the clamping assembly 12 includes a first clamping member 121 and a second clamping member 122, and the first clamping member 121 and the second clamping member 122 are respectively pivotally connected to the first lever 111 and the second lever 112, so that the first lever 111 and the second lever 112 manipulate the relative position between the first clamping member 121 and the second clamping member 122. The first clamping member 121 extends outward from the first operating rod 111, the first operating rod 111 and the first clamping member 121 are L-shaped, the second clamping member 122 extends outward from the second operating rod 112, and the second operating rod 112 and the second clamping member 122 are L-shaped. And the first clamping member 121 and the second clamping member 122 have a certain preset height, respectively, and the first clamping member 121 and the second clamping member 122 have the same height, so that the positioning device 20 is disposed in a space formed by the first clamping member 121 and the second clamping member 122. In other words, the first clamping member 121 extends from the first operating rod 111 to form a first clamping surface, the second clamping member 122 extends from the second operating rod 112 to form a second clamping surface, the first clamping surface and the second clamping surface are respectively located on two sides of the operating assembly 11, and the first clamping surface is opposite to the second clamping surface, and the first clamping surface and the second clamping surface form the space.

Further, the first clamping member 121 includes a set of first clamping arms 1211 and a first extension arm 1212, each of the first clamping arms 1211 extends downward from the first extension arm 1212, and the first clamping arms 1211 have a predetermined length, each of the first clamping arms 1211 has a predetermined distance therebetween, and each of the first clamping members 121 provides a clamping force to the steel plate when the first clamping member 121 acts on the steel plate. It should be noted that the first clamping arm 1211 has a first hook mechanism 12111, the first clamping arm 1211 is connected to the steel plate by the first hook mechanism 12111 in a snap fit manner, and the first hook mechanism 12111 is matched with the thickness of the steel plate so as to increase the connection between the first clamping member 121 and the steel plate.

Further, the second clamping member 122 includes a set of second clamping arms 1221 and a second extension arm 1222, each of the second clamping arms 1221 extends downward from the second extension arm 1222, and the second clamping arms 1221 have a predetermined length, each of the second clamping arms 1221 have a predetermined distance therebetween, and each of the second clamping members 122 provides a clamping force to the steel plate when the second clamping member 122 acts on the steel plate. It should be noted that the second clamping arm 1221 has a second hook mechanism 12211, the second clamping arm 1221 is connected to the steel plate by the second hook mechanism 12211 in a snap fit manner, and the second hook mechanism 12211 is matched with the thickness of the steel plate to increase the connection between the second clamping member 122 and the steel plate.

It should be noted that the first extension arm 1212 has a first sliding slot 12120, and an end of the first operating lever 111 is slidably disposed in the first sliding slot 12120; the second extension arm 1222 has a second sliding channel 12220, and an end of the second lever 112 is slidably disposed in the second sliding channel 12220. Further, when the user applies force to the first lever 111 and the second lever 112, the ends of the first lever 111 and the second lever 112 slide on the first slide groove 12120 and the second slide groove 12220, respectively, to control the relative positions between the first clamp member 121 and the second clamp member 122.

It should be noted that the fixing device 10 includes an adjusting component 13, the adjusting component 13 is disposed on the operating component 11, the adjusting component 13 can maintain the opening size of the clamping component 12, and the adjusting component 13 enables the fixing device 10 to have a reset function, so as to reduce the acting force of a user on the fixing device 10. Further, the adjusting unit 13 includes an adjusting member 131, the adjusting member 131 is disposed between two ends of the first lever 111 and the second lever 112, when a user applies a force to the first lever 111 and the second lever 112, the first lever 111 and the second lever 112 slide on the adjusting member 131, respectively, and when the end of the first lever 111 is close to the end of the second lever 112, the other ends of the first lever 111 and the second lever 112 slide on the first slide groove 12120 and the second slide groove 12220, respectively, and then the opening between the first clamp 121 and the second clamp 122 increases, so that the fixing device 10 is adapted to the steel plate having a larger size. Conversely, when the first and

second levers

111 and 112 are slid on the adjustment members 131, respectively, and the end portions of the first and

second levers

111 and 112 are separated from the end portions of the second levers 112, the other end portions of the first and

second levers

111 and 112 are slid on the first and

second slide grooves

12120 and 12220, respectively, and thus the openings between the first and

second clamping members

121 and 122 are reduced, so that the fixing device 10 is adapted to the steel plate having a smaller size. In other words, when the user operates the operating member 11, the state restoration of the regulating member 131 changes as the user applies an example force to the operating member 11, and when the external force applied to the operating member 11 by the user is withdrawn, the state of the regulating member 131 is not changed any more, and the regulating member 131 enables the operating member 11 to be maintained in the regulated state, which is particularly important for convenience in use of the gripping apparatus.

Preferably, the adjusting member 131 is a sliding bar having a tooth structure, the first operating rod 111 and the second operating rod 112 are respectively slid on the sliding bar, and the first operating rod 111 and the second operating rod 112 are respectively maintained in the adjusted state due to the tooth structure, and thus the fixing device 10 is maintained in the adjusted open size due to the adjusting member 131. Only when the first and

second levers

111 and 112 exert a force, the relative positions of the first and

second levers

111 and 112 at the regulating member 131 are regulated to be changed.

When the relative positions of the first lever 111 and the second lever 112 are changed by the force, the state of the elastic member 132 is changed, and thus elastic deformation occurs, and the elastic member 132 has a change to return to the original state. Therefore, the elastic member 132 can reduce the force applied to the operating assembly 11 by the user, thereby facilitating the use of the device. Preferably, the elastic member 132 is a set of elastic pieces 1321, each elastic piece 1321 is disposed on the first lever 111 and the second lever 112, and the other ends of the elastic pieces are connected, so that when the first lever 111 and the second lever 112 slide on the adjusting member 131 in a stressed state, elastic deformation occurs between each elastic piece 1321, and the elastic pieces 1321 enable the operating assembly 11 to have a restoring and reducing effect. Preferably, the elastic member 132 is a spring 1322, the spring 1322 is disposed between the first lever 111 and the second lever 112, and the spring 1322 enables the operating assembly 11 to have a function of restoring and reducing an acting force.

In other words, the grip assembly 21 is detachably mounted to the fixture 10. Preferably, the grip assembly 21 is detachably mounted to the connector 14 of the fixture 10. Optionally, the grip assembly 21 is adjustably positioned to the connector 14 of the fixture 10.

Further, the holding assembly 21 includes a support arm 212, and the support arm 212 extends outwardly from an end of the positioning member 22 and forms a predetermined angle with the positioning member 22.
