Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of interior row's anchor with inverted tooth needle for treating rotator cuff tear
Nail.
Background technology
In current surgical operation, the mode for shoulder sleeve repairing includes mainly wearing bone fixation technology, single technology, tradition
Double technology and the suture double suturing skill of bridge.Wherein, double suture can increase tendon bone contact area, reduce shoulder sleeve crack shape
At increasing the maximum failure load of suture and provide stronger initial biomechanical strength, relative to single suture and wear bone
The coverage rate higher of ligamentopexis shoulder sleeve stop.External medical investigator by studying energetically in this respect, it was confirmed that double seam
This advantage, such as Kim etc. closed single double biomechanics experiment relatively in, confirm that double suture initial strength is better than
It is single, then fracture rate, again smaller than single suture, abduction muscular strength recovery situation is more excellent, is less than the double sewing of 3cm rotator cuff injury lists
Function score no significant difference after treatment, the rotator cuff injury more than 3cm can get more using the more single sewing of double sewing
Excellent postoperative function scoring.
However, double suture also has shortcoming：(1) surgical procedure difficulty increases, and tucking inside the sleeve across shoulder, the end of a thread is more, and the time is more
Long, treatment future trouble shoulder swelling degree aggravates；(2) patient's stand up time is longer, both arms operation it is longer, can be formed biped with and both arms
Accessory injury；(3) if loosening deficiency in double suture treatment, tension bigger is sutured after treatment, is easily caused suture cutting tendon and is made
Possibility is torn again at shoulder sleeve；(4) patient's anesthesia duration is longer, risk bigger.The shortcomings that for double suture, the application devises
A kind of interior row's holdfast of shoulder sleeve suture, can greatly shorten operation time, and can make holdfast line tail substep evenly, and
Shoulder sleeve tendon cutting can be reduced, the success of bigger is can get.
Invention content
The object of the present invention is to provide a kind of interior row's holdfasts with inverted tooth needle for treating rotator cuff tear, solve existing
The problem of it is big that there are operation difficulties in technology, and operating time is long and suture cutting tendon causes shoulder sleeve to tear again.
The technical solution adopted in the present invention is that interior row's holdfast with inverted tooth needle for treating rotator cuff tear includes holdfast
Ontology, ground anchor body outer wall offer screw thread, axially and symmetrically open up that there are four groove, ground anchor bodies on the outside of screw thread along ground anchor body
Middle part is radially also opened there are two through-hole, is mutually perpendicular between the axis of two through-holes, one end of each groove with through-hole
One end is connected to, the affixed inverted tooth needle in the one end of each groove far from through-hole.
The axis of through-hole is mutually perpendicular to the axis of ground anchor body, and the circular in cross-section of through-hole.
Ground anchor body end face center offers interior hex slot, and the ground anchor body other end is in cone.
Groove is located at through-hole and ground anchor body offers between one end of interior hex slot.
Inverted tooth needle is located at the surface that ground anchor body offers interior hex slot one end.
Inverted tooth needle one end is tapered, and pin hole is provided on the tapered one end of inverted tooth needle, and the other end radius of inverted tooth needle is less than
The radius of inverted tooth needle needle body.
The cross section of groove is semicircle, rectangle or trapezoidal.
The outer edge of screw thread and groove is that rounding is angular.
The invention has the advantages that interior row's holdfast with inverted tooth needle for treating rotator cuff tear, solves existing skill
The problem of it is big that there are operation difficulties in art, and operating time is long and suture cutting tendon causes shoulder sleeve to tear again.The one of the present invention
Kind can greatly shorten operation time for treating interior row's holdfast with inverted tooth needle of rotator cuff tear, and can make holdfast line tail
Bar substep evenly, and can reduce shoulder sleeve tendon cutting, so that operation is obtained the success of bigger, and with simple in structure, manufacture
It is easy, surgical procedure is easy, reduces damage and fixed reliable advantage.

Specific implementation mode
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Interior row's holdfast with inverted tooth needle for treating rotator cuff tear of the present invention, as shown in Figure 1, include ground anchor body 1,
1 outer wall of ground anchor body offers screw thread 2,2 outside of screw thread axially and symmetrically opened up along ground anchor body 1 there are four groove 5, ground anchor body
1 middle part is radially also opened to be mutually perpendicular between the axis of two through-holes 4 as shown in Figures 2 and 3 there are two through-hole 4, each recessed
One end of slot 5 is connected to one end of through-hole 4, the one end of each groove 5 far from through-hole 4 affixed inverted tooth needle 6.
Axis of the axis of through-hole 4 with ground anchor body 1 is mutually perpendicular to, and the circular in cross-section of through-hole 4.
As shown in figure 4,1 end face center of ground anchor body offers interior hex slot 3,1 other end of ground anchor body is in cone.
Groove 5 is located at through-hole 4 and ground anchor body 1 offers between one end of interior hex slot 3.
Inverted tooth needle 6 is located at the surface that ground anchor body 1 offers 3 one end of interior hex slot.
6 one end of inverted tooth needle is tapered, and pin hole is provided on the tapered one end of inverted tooth needle 6, and the other end radius of inverted tooth needle 6 is small
In the radius of 6 needle body of inverted tooth needle.
The cross section of groove 5 is semicircle, rectangle or trapezoidal.
The outer edge of screw thread 2 and groove 5 is that rounding is angular.
The operation principle of interior row's holdfast with inverted tooth needle for treating rotator cuff tear of the present invention is that 2 center of screw thread is opened
Two cross through hole 4, for passing through for medical suture, 5 slot of groove of 2 surrounding symmetry of screw thread is worn for suture from through-hole 4
Later it is laterally penetrated along groove 5, by groove 5, suture is upward through into the pin hole on 6 one end of inverted tooth needle, to draw
Go out suture, since the needle body radius of the radius ratio inverted tooth needle 6 of the other end of inverted tooth needle is small, so can be rolled over along the other end of inverted tooth needle
It is disconnected, to achieve the effect that suture, one end center of ground anchor body 1 are provided with Hexagon hole, sclerotin can be screwed into interior hexagonal screwdriver.
The application method of interior row's holdfast with inverted tooth needle for treating rotator cuff tear of the present invention is, when being performed the operation,
Operator is under the monitoring of arthroscope, after ground anchor body 1 is screwed into sclerotin, then shoulder sleeve is won over, is uniformly pressed in inverted tooth needle 6
On, in this way, four inverted tooth needles 6 both pass through shoulder sleeve with line, and it is uniformly distributed, suture is then caught with wire gripper, and the pawl that fractures
Needle 6, such shoulder sleeve suture terminate, and the function of interior row's holdfast just terminates.
