Description

Knee joint valgus assistor

Technical Field

The utility model relates to a medical science inspection auxiliary instrument technical field, concretely relates to knee joint assistor that turns up.

Background

Injury to the medial collateral ligament of the knee joint is a type of injury to the knee joint commonly found in physical labor and sports activities. Injury to the medial collateral ligaments of the knee joint can occur when the knee joint is subjected to sudden violent forces, particularly sudden eversion or external rotation in a straightened or flexed position.

In order to determine the degree of injury of the medial collateral ligament of the knee joint, the clinician needs to take an image of the knee joint tension sheet. In the process of shooting the knee joint tension position sheet, the leg of the patient needs to be turned outwards by assistance of family members or medical personnel, and the X-ray existing in the shooting environment can threaten the body health of the family members or the medical personnel.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to foretell technical current situation and provide a knee joint auxiliary device that turns up, enable the doctor and accomplish knee joint tension position piece alone and shoot, need not family members or medical personnel auxiliary operation.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a knee joint valgus assistor which characterized in that: the leg supporting device is used for being arranged between legs of a patient and comprises a supporting rod and arc-shaped plates arranged at two ends of the supporting rod respectively, and the concave parts of the arc-shaped plates are arranged outwards and used for supporting the inner sides of the legs of the patient.

In order to adjust the length of the stay bar to adapt to patients of different ages and different physical conditions, the stay bar is a telescopic bar.

But as the concrete design of telescopic link, the vaulting pole is including the outer pole and the interior pole of establishing of mutual cover, just wear to be equipped with the holding screw that can compress tightly interior pole on the outer pole and pass through the infinitely variable control of holding screw realization interior outer pole relative position. The relative position of interior outer pole can also be fixed through the buckle structure of mutually supporting to this department inside and outside pole to realize the length adjustment of vaulting pole. If the outer rod is provided with a plurality of clamping holes, the inner rod is provided with an elastic convex column; or a matching locking structure of the tapered threaded rod and the expansion sleeve is arranged between the inner rod and the outer rod, or other structures capable of adjusting the length of the stay bar.

In a further design, the outer rod and the inner rod are square tubes. More preferably, when the stay bar is a telescopic bar, the design of the square bar can prevent the radial position deflection between the inner bar and the outer bar in the process of adjusting the length of the stay bar. The square rod can be a rod body with the cross section in other shapes, such as a hexagon, a pentagon and the like, or a rotation limiting structure is arranged between the inner rod and the outer rod, and the relative rotation between the inner rod and the outer rod can be limited as long as the connection between the inner rod and the outer rod can be met.

In order to make the legs of the patient more comfortable when in use, the concave part is provided with a spongy cushion. The spongy cushion can be a cotton bag cushion or a silica gel cushion. The foam-rubber cushion can be fixed in the concave part in an adhesion mode or a detachable mode, and specifically, the foam-rubber cushion can be fixed in the concave part in a detachable mode such as a rope system, a double-faced adhesive tape, a thread gluing and the like. More preferably, the thickness of the spongy cushion is not too thick, otherwise the accuracy of mastering the actual force application strength of the support rod by a doctor is influenced.

Compared with the prior art, the utility model has the advantages of: the knee joint tension sheet shooting device can continuously apply force to the knee joint of a patient, so that a doctor can independently complete the knee joint tension sheet shooting process without assistance of family members or other medical personnel, and the X-ray threat to the health of the family members or other medical personnel is avoided; the telescopic rod of the support rod is suitable for patients of different ages and physical conditions, and doctors can adjust the length of the support rod according to actual needs so as to adjust force application force; the arc-shaped plate can be attached to the legs of the human crus, and the spongy cushion is additionally arranged, so that the comfort level of a patient is improved; simple structure and convenient operation.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

A preferred embodiment of the present invention is shown in fig. 1-3.

As shown in fig. 1 to 3, the valgus assist device for knee joint comprises a stay bar 1, an arc plate 2 and a set screw 3.

As shown in fig. 1-2, the stay bar 1 is a telescopic bar. The stay bar 1 comprises an inner bar 12 and an outer bar 11 movably sleeved outside the inner bar 12. The relative positional relationship between the inner and outer rods is fixed by a set screw 3. Specifically, the set screw 3 is arranged on the outer rod 11 in a penetrating manner, the surface of the inner rod 12 is pressed tightly, and the length of the stay bar 1 is adjusted steplessly through the set screw 3.

In other embodiments, the relative positions of the inner rod and the outer rod can be fixed through mutually matched buckling structures, so that the length adjustment of the stay bar is realized. If the outer rod 11 is provided with a plurality of clamping holes, the inner rod 12 is provided with an elastic convex column; or a matched locking structure of a conical threaded rod and an expansion sleeve is arranged between the inner rod and the outer rod.

As shown in fig. 1-2, the outer rod 11 and the inner rod 12 are square tubes, which can limit the relative rotation of the inner rod and the outer rod during the movement process. In other embodiments, other structures capable of limiting the relative rotation of the inner rod and the outer rod may be provided between the inner rod and the outer rod, for example, a rib-groove matching guide structure is provided between the inner rod and the outer rod, or the cross section of the stay bar 1 is pentagonal, hexagonal, or the like.

As shown in fig. 1-2, the number of the arc plates 2 is 2, and the arc plates are respectively arranged at two ends of the stay bar 1. The recess 20 of the arcuate plate 2 is disposed outwardly for abutment against the lower leg of the patient. In other embodiments, the concave portion 20 is further provided with a cushion made of a softer material, such as a sponge cushion, a cotton bag or a silica gel cushion, so that the patient can feel more comfortable when using the cushion.

As shown in fig. 3, the working principle of this embodiment is as follows: when the patient claps knee joint tension position piece, tie up bandage 4 of tightening on patient's thigh shank 51, place the knee joint assistor of turning up between patient's shank 53, thereby adjust the relative fixed position of interior outer pole through rotatory holding screw 3 and adjust vaulting pole 1 length for the demand of the actual application of force size of adaptation to the patient, and make the concave part 20 of the arc 2 at both ends support patient's shank 53 respectively, can shoot patient's knee joint 52.

The knee joint tension position piece of this embodiment can be continuously to patient's knee joint application of force, makes the doctor can accomplish knee joint tension position piece alone and shoots the process, need not family members or other medical personnel to assist, has avoided X ray threat family members or other medical personnel's healthy.
