The heel tendon minimally invasive anastomat comprises a ring plier body, and the ring plier body comprises a left plier body and a right plier body which are hinged with each other. The heel tendon minimally invasive anastomat is characterized in that an aiming support is further arranged at the hinged position of the left plier body and the right plier body, the aiming support comprises two aiming arms which extend in the opening directions of clamping parts of the ring plier body, the two aiming arms are located on the two sides of the ring plier body respectively, and threading holes are formed in the ends of the two aiming arms. The heel tendon minimally invasive anastomat has the advantages of being small in wound, shortening operating time, avoiding heel tendon distortion and excursion after suture, preventing the eccentric phenomenon of sagittal view suture, being low in cost and the like, thereby having the good industrialization prospect and market value.

Description

A kind of heel string invasive anastomat

Technical field

The present invention relates to medical instruments field, particularly relate to a kind of heel string invasive anastomat.

Background technology

Heel string be in human body the most slightly, the most powerful tendon, be about 15cm, it is positioned at lower segment leg rear, connect triceps surae and calcaneus, its major function is the plantar flexion of responsible ankle joint, play an important role for completing of action such as walking, running, jumps, after rupture of Achilles tendon, the walking function of patient will be had a strong impact on.Fresh Rupture of Achilles Tendons is common in motion, and in recent years, its incidence rate constantly increases, and this and the interest of people to physical training constantly increase, participation amount constantly increases, and cause heel string chronic strain relevant; The ratio of also living with people's official documents or correspondence work on ordinary days and static state is higher, but leisure time participates in suddenly the stress-relieving activity that quantity of motion is comparatively large, difficulty is higher again, and the motion that heel string cannot bear this unexpected over loading is relevant; The tendon Quality Down that multiple chronic disease causes simultaneously also easily causes rupture of Achilles tendon.In all rupture of Achilles tendon cases, the case more than 75% is the sporter of 30 ~ 50 years old age bracket in sports.

Fresh Rupture of Achilles Tendons is common motor system damage, and report display incidence rate is 18,/10 ten thousand, and in rising trend; Therapeutic Method mainly contains expectant treatment and the treatment of traditional cutting operation.Research shows, the expectant treatment heel string incidence rate that ruptures again is 8%-29%, has a strong impact on patient's function.And traditional incision operation energy exactitude position fracture heel string, obtain certain curative effect, significantly reduce the generation of rupturing again, but its operation wound is comparatively large, there is the complication such as infection of incisional wound, nerve injury, cicatricial adhesion, thus affect ankle joint function recovery.Therefore find new therapeutic method of surgery and seem very necessary.

Excessively peel off in view of traditional operation and expose the problem that causes, best solution is exactly reduce soft tissue injury scope in operation process and degree to greatest extent.The Minimally Invasive Surgery of Fresh Rupture of Achilles Tendons has had certain progress in recent years.Someone heel string of percutaneous suture fracture is respond well, but this method easy damaged sural nerve, sometimes even need re-treatm ent to carry out nerve and loosen; In addition, because the tendon broken ends of fractured bone can not be looked at straight, the quality that the broken ends of fractured bone is repaired can not be ensured, fracture and achilles tendon lengthening more easily occur.Somebody adopts the auxiliary lower percutaneous suture treatment Fresh Occlusive rupture of Achilles tendon good results of arthroscope, but arthroscope equipment price is expensive, is difficult to promote at Grass-roots Hospital.

Due to improving constantly of compatriots' living standard, the sickness rate of relevant heel string pathological changes also promotes to some extent, and for ever-increasing heel string operative effect demand, the improvement for operating theater instruments is very important.

Summary of the invention

The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of heel string invasive anastomat and uses thereof, for solving the problems of the prior art.

For achieving the above object and other relevant objects, first aspect present invention provides a kind of heel string invasive anastomat, comprise ring clamp body, described ring clamp body comprises mutually hinged left caliper and right caliper body, it is characterized in that, the hinged place of described left caliper and right caliper body is also provided with collimation support, described collimation support comprises the aiming arm that two opening directions to ring clamp body clamping part extend, described two aiming arms lay respectively at the both sides of ring clamp body, and the end of described two aiming arms is equipped with through wires hole.

Preferably, the mutual one_to_one corresponding of through wires hole of the end of described two aiming arms.

Preferred, the end of described two aiming arms is equipped with 2 through wires holes.

Preferred, described collimation support is U-shaped body, and the opening direction of described U-shaped body is identical with the opening direction of ring clamp body clamping part, and two aiming arms are parallel to each other.

Preferred further, the distance between described two aiming arms is 88-92mm.

Preferred further, on the aiming arm of side, the aperture of through wires hole is 5-7mm, and on opposite side aiming arm, the aperture of through wires hole is 1.8-2.2mm.

Preferably, described ring clamp body clamping part is provided with holding ring, and when ring clamp body is in clamp position, on described aiming arm, the line of through wires hole in correspondence with each other all runs through the holding ring of ring clamp body clamping part.

Preferably, the clamping part of described ring clamp body and the angle of clamp handle are 145-155 °.

Preferably, locked part is equipped with inside two clamp handles of described ring clamp body.

Second aspect present invention provides the purposes of described heel string invasive anastomat in heel string Minimally Invasive Surgery.

As mentioned above, heel string invasive anastomat provided by the present invention, has following beneficial effect:

1, wound little (otch 1.5-2 centimetre), especially little for destroying to local blood, not easily there is the incision complication such as postoperative wound infection or cutaneous necrosis; Incisional scar is little, more attractive in appearance.

2, the heel string broken ends of fractured bone that to coincide with percutaneous threading can be appeared by minimal incision *, not only reduce soft tissue and expose and damage range, and reduce adhesion of tendon thus and shorten operating time (about 20-30 minute)

3, after the heel string broken ends of fractured bone is fixed in tissue forceps traction relatively, utilize heel string invasive anastomat, operator can use the ring clamp of hand operated heel string invasive anastomat, by the subcutaneous heel string utilizing holding ring to clamp fracture, after make it and heel string axis oriented normal according to outside diopter when penetrating suture, thus can ensure that suture passes perpendicularly through heel string, can avoid sewing up rear heel string distortion and skew generation.

4, after the heel string broken ends of fractured bone is fixed in tissue forceps traction relatively, utilize heel string invasive anastomat, operator can clamp the heel string of fracture with hands, after can ensure that suture passes perpendicularly through the axis (not eccentric) of heel string when penetrating suture, prevent sagittal plain from sewing up eccentric.

5, because in operation process, foot be kept in plantar flexion position, and the clamping part of heel string invasive anastomat ring clamp body and the angle design of clamp handle can effectively increase operation technique space always.

6, different according to fracture location, arbitrarily can regulate position and the interval of threading.

7, in addition, the present invention is with low cost, has good industrialization prospect and market value.
