Detailed Description

The present application is described in further detail below with reference to the attached drawings.

Referring to fig. 2, the present application provides a tendon stripper, which comprises a hand-held part 2 and a scraper 1 for stripping tendons, wherein the hand-held part 2 and the scraper 1 are integrally formed; the edge of one side of the handheld part 2, which is far away from the scraper 1, is arc-shaped, and the circle center of the arc-shaped edge is positioned on one side of the handheld part 2, which is close to the scraper 1, namely the edge of the handheld part 2 protrudes outwards in the direction far away from the scraper 1; one surface of the squeegee 1 is obliquely close to the other surface of the squeegee 1 in a direction from close to far from the hand-held portion 2, that is, the thickness of the squeegee 1 becomes thinner gradually in a direction from close to far from the hand-held portion 2; eight measuring holes 3 with different diameters and penetrating through the handheld part 2 are formed in the handheld part 2, when the thickness of the taken tendon needs to be measured, the end of the tendon is aligned to the measuring hole 3 and inserted into the measuring hole 3, and if the tendon cannot pass through a certain measuring hole 3, the diameter of the tendon is larger than that of the measured hole 3; at this time, a large number of measuring holes 3 are selected and the tendon is inserted into the measuring holes 3, if the tendon just can pass through a certain measuring hole 3, the diameter of the measuring holes 3 is approximately equal to the thickness of the tendon, the thickness of the tendon is measured, and a doctor can select a screw with a proper type according to the thickness of the tendon; the measuring tool does not need to be replaced after the tendon is taken down, so that the integration of the tendon stripping function and the tendon thickness measuring function is realized, and the efficiency of the tendon suture operation is further improved.

When a doctor peels off tendons, the doctor needs to hold the hand-held part 2 and the scraper 1 and bend the hand towards the palm center, and the palm center of the palm forms an arc shape; because the handheld portion 2 keeps away from a side edge of scraper blade 1 and is arc, and then when one side and the palm of the palm department butt that scraper blade 1 was kept away from to handheld portion 2, handheld portion 2 can adapt to the shape of palm better, makes things convenient for doctor to grab on the one hand and holds handheld portion 2, and on the other hand improves doctor and grabs the comfort level that handheld portion 2 was held. In addition, the thickness of the scraper 1 becomes gradually thinner along the direction from the approach to the holding part 2, and when tendon separation is performed, the part of the scraper 1 far from the holding part 2 is thinner, so that tendon separation can be performed more accurately; on the other hand, the weight of the scraper 1 can be reduced, and the labor intensity of a medical worker in the operation process can be reduced.

Referring to fig. 2 and 3, further, a plurality of measuring holes 3 are uniformly distributed along the circumferential direction of the circular arc edge of the hand-held portion 2; the diameters of the plurality of measuring holes 3 become larger gradually along the direction from the two sides of the handheld part 2 to the middle position; furthermore, on the side of each measuring orifice 3 close to the scraper 1, there are provided values corresponding to the diameters of the two orifices, which in the present embodiment are, in order from the side of the hand-held part 2 to the other: 5.5mm, 6.0mm, 6.5mm, 7.0mm, 9.0mm, 8.5mm, 8.0mm, 7.5mm, the diameter of the metering orifice 3 on the hand grip 2 and corresponding values include, but are not limited to, the values mentioned above.

A plurality of line passing holes 4 which are respectively communicated with the corresponding measuring holes 3 are formed in the arc edge of the handheld part 2, the line passing holes 4 extend from the measuring holes 3 to the arc edge of the handheld part 2 and are communicated with the outer side of the handheld part 2, and the width of each line passing hole 4 is larger than the diameter of a suture line so that the suture line can pass through; furthermore, the thread through hole 4 extends in the radial direction of the arc-shaped edge of the hand grip 2 and at the same time extends in the radial direction of the metering orifice 3. Before the tendons taken from other parts of the human body are transplanted and sutured, the taken tendons need to be folded in half according to a plurality of equal parts, and then the diameters of the tendons are enlarged to meet the transplanting requirements of the tendons; after the folding is finished, the folded tendon is sewn and woven by using a suture line, and the thread end of the suture line is exposed outside the tendon; when the tendon thickness after the fifty percent discount needs to be measured, make the end of a thread of stylolite enter into the graduated bore 3 inside through crossing the line hole 4, draw the stylolite along certain direction so that the tendon moves to the direction that is close to the graduated bore 3, made things convenient for like this to make the tendon pass through corresponding graduated bore 3. In addition, because cross radial extension of line hole 4 along the arc edge of handheld portion 2 to simultaneously along the radial extension of graduated flask 3, at the radial department that graduated flask 3 and handheld portion 2 arc edges are public, the distance of graduated flask 3 apart from handheld portion 2 edges is the shortest, crosses line hole 4 and sets up and to shorten the processing route of crossing line hole 4 and then conveniently process in this department.

Further, a series of scale marks 5 are arranged on the surface of the scraper 1, and the scale marks 5 are arranged at the edge of the scraper 1 far away from the handheld part 2; when the length of the removed tendon needs to be measured, the tendon is aligned to the scale mark 5 at the edge of the scraper blade 1 for measurement, so that the length measuring instrument does not need to be replaced, the scraper blade 1 is directly used, the integration of the tendon peeling function and the tendon length measuring function is realized, and the efficiency of the tendon suture operation is further improved.

The handheld portion 2 all is provided with the radius angle with the edge of being connected transition position, handheld portion 2 of scraper blade 1 and the edge of scraper blade 1, and the radius angle can reduce tendon stripper's marginal pointed end, and then reduces scraper blade 1 or handheld portion 2 and causes the possibility of stab or even tissue necrosis to colliding with of tissue around the tendon to feel when having improved tendon stripper is handheld.

To sum up, the application process of this application is: the tendon is peeled off by using the scraper 1, when the diameter of the tendon needs to be measured, the thread end of the suture thread enters the measuring hole 3 through the thread passing hole 4 and is dragged to move the tendon towards the direction close to the measuring hole 3, and if the tendon cannot pass through a certain measuring hole 3, the diameter of the tendon is larger than the diameter of the measured measuring hole 3; at the moment, a first measuring hole 3 is selected and the tendon is inserted into the measuring hole 3, if the tendon just can pass through a certain measuring hole 3, the diameter of the measuring hole 3 is approximately equal to the thickness of the tendon, and the thickness of the tendon is measured; when the diameter of the tendon needs to be measured, the tendon is aligned to the scale mark 5 on the edge of the scraper 1 for measurement; thus, the integration of the tendon stripping function, the tendon thickness measuring function and the tendon length measuring function is realized, and the efficiency of the tendon suture operation is improved.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
