Needle holder is an essential apparatus indispensable when sewing up wound in the surgical operation.The present needle holder that uses clinically, the main shape that supports needle body before it mostly is the scissors structure, and promptly two clamping monomers are articulated and connected with the form of cutting shape and form, and as a kind of shape of crevice tool pincers, only volume is littler, and length is longer.And the suture needle clamping of this scissors needle holder is to realize by the opening and closing left and right that scissors are held needle body, therefore when making endoceliac suture operation, use this class needle holder to be especially careful, because along with the insertion and extract of suture needle in sewing process hockets, holding the folding of needle body also advances along sutural margin, soft tissue around accidentally injuring easily on the one hand, the scissors of this class opening and closing left and right formula are held needle body on the other hand, need reserve bigger scalpel edge in advance at body surface, finish with turnover that makes things convenient for this apparatus and the action that guarantees opening and closing left and right.
Along with the raising of medical technique level, the needle holder that some volumes are littler, hold the little different shape of needle body folding scope has appearred, to adapt to current popular micro-wound surgical operation.But there is a kind of defective in all at present needle holders, can not freely change the angle of holding pin at any time exactly in art.Because as the suture needle occlusal surface of holding on the needle body all be usually and the perpendicular plane of the main shaft of this needle holder, so the suture needle that clamping is lived is vertical with this needle holder.Like this, if when sewing up with sutural margin that the needle holder main shaft parallels, suture needle and sutural margin are perpendicular, and at this moment sew application is understood more convenient; And if sutural margin and needle holder major axis be when perpendicular, suture needle is parallel with sutural margin, and sew application is will difficulty very big; General doctor is change lever position ceaselessly, holds the orientation angle of needle body with adjustment; If run into the dark but less operation of surface cuts in suture site, the handle activity space of needle holder just often is restricted, and can only be continued by suture needle is tiltedly pressed from both sides just under a lot of situations; But tiltedly the angle of pressing from both sides can not be excessive, is because of operating difficulties on the one hand, and the suture needle behind the oblique on the other hand folder is easy to change angle, and present stage also is not convenient to the needle holder of oblique crack pin in application.
Below as can be known, modern medicine press for clinically a kind of can be under the situation of the little otch of body surface, make the suture needle of clamping can make freedom, reliable angular transition within the specific limits, to carry out the fixed angle type needle holder of deep suture operation smoothly satisfactorily, with the Wicresoft that adapts to the modern medicine surgery, the specific (special) requirements of little otch.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of can be under the situation of the little otch of body surface, the clamping angle of suture needle can change in certain scope, and suture needle be difficult for slippage or rotation, can reliably carry out the deep sew application, the fixed angle type needle holder of easy damaged surrounding tissue not again simultaneously.
To achieve these goals, technical scheme of the present invention is:
A kind of fixed angle type needle holder comprises the operating grip that needle body and rear end are held of holding that is positioned at front end, and the described needle body of holding is made up of the chuck and the chuck of two coaxial line activities, has the occlusal surface that coincide mutually between chuck and the chuck; Described chuck is fixed on the bottom of a hollow outer tube, and described chuck is fixed on the bottom of pull bar, and described pull bar is inserted in the outer tube and with outer tube and is movably connected.
As the further improvement of fixed angle type needle holder of the present invention, an inclination angle is arranged between the main shaft of described occlusal surface and needle holder.
As the further improvement of fixed angle type needle holder of the present invention, described angle of inclination value is between 45 degree-90 degree.
As the further improvement of fixed angle type needle holder of the present invention, described angle of inclination value is 70 degree.
As the further improvement of fixed angle type needle holder of the present invention, described occlusal surface is provided with the grinding tooth that increases friction effect.
As the further improvement of fixed angle type needle holder of the present invention, have the Saw blade of using as stop bit on the described operating grip 9.
Fixed angle type needle holder of the present invention adopts a kind of structure of loop type, but constitutes the needle body of holding of clamping suture needle with two coaxial straight-line active chucks.This structure of holding needle body does not have traditional scissors to hold the horizontal open and close movement of needle body, so work surface is little, can not influence its surrounding tissue; Therefore the occlusal surface between these two chucks and the main shaft of needle holder are not perpendicular, but have the angle of certain inclination, during according to the occlusal diverse location of suture needle place of clamping, the different pin angles (with respect to the main shaft of needle holder) of holding can occur; This pin angle of holding can be vertical, also can suture needle be placed again on the difference of occlusal surface curve by the axostylus axostyle of rotation needle holder, and conversion makes new advances holds the pin angle; And, because the suture needle body also is a kind of shape as crotch, therefore, the location point difference that is held, the needle point of suture needle points to also different; Suture needle body on the same point also can rotate in the angles at 180 degree, so the various pin angle of holding has been brought up in the position of suture needle and sensing.Like this, the doctor in the operation can hold the approach axis of needle body by the operating grip adjustment, makes suture needle with on the diverse location in the various angle incision occlusal surfaces, and can be clamped by last lower chuck front, to realize that fixed angle type is held pin at any angle.Can have the grinding tooth that increases friction effect on the occlusal surface, be convenient to clamp more firmly suture needle; Operating grip also has one can fall Saw blade as what stop bit was used, and handle can not unclamped from pinning after clamping, is convenient to operative doctor and only is absorbed in power in using the pin position.

The specific embodiment
In order further to illustrate technical scheme of the present invention, below will describe specific embodiment in detail.
As shown in Figure 1, fixed angle type needle holder of the present invention adopts medical stainless steel or other medical hard metal material to make, and the needle body of holding of its front end is made up of the chuck 1 and the chuck 2 of two coaxial line activities, and the rear end is the operating grip of holding 8.Handle 8 is similar with the handle of traditional scissors needle holder, is the finger ring handle of opening and closing left and right, is well suited for dexterous the use; Respectively be provided with one at the place of colliding of two pommels and can fall Saw blade 9 as what stop bit was used, can only do unidirectional motion after the engagement between its teeth, handle 8 can only inwardly be closed can not be to external-open, prevent that with the strength that maintains the folder pin accident of suture needle from pitching or dislocating, and also be beneficial to the more absorbed power of operative doctor in using the pin position.
As shown in Figure 2, chuck 2 is fixed on the bottom of the outer tube 3 of an elongated hollow, is hollow cylinder, and its external diameter is identical with the external diameter that is all columniform chuck 1, and internal diameter is identical with the internal diameter of outer tube 3; Chuck 1 is fixed on the bottom of an elongated pull bar 4, and the external diameter of pull bar 4 is slightly less than the internal diameter of outer tube 3, makes pull bar 4 can be inserted in the outer tube 3 and with outer tube 3 and is movably connected; Have the occlusal surface that mutually coincide between chuck 1 and the chuck 2, between the main shaft of this occlusal surface and needle holder (being the axle of pull bar 4 and outer tube 3) and out of plumb, but have certain angle of inclination, this angle value be in 45 spend-90 spend between.This occlusal angle of inclination value is 70 degree in this specific embodiment, promptly with the perpendicular plane deflection 20 degree angles of main shaft, uses maximum values for holding pin angle excursion.
Distributing on the occlusal surface to increase the grinding tooth of friction effect 10, and grinding tooth 10 is that the lines with a kind of cross-distribution is located at respectively in the engagement surface of chuck separately, holds suture needle to reach to sting securely, avoids phenomenons such as needle body skids.
Therefore the build of fixed angle type needle holder of the present invention is elongated, and the round external diameter of chuck 1 and chuck 2 also just is slightly larger than the external diameter of outer tube 3, is beneficial to make the needle body of holding of front end stretch in the body cavity and carry out folding work up and down from the little incision of body surface very much; Outer tube 3 links to each other with handle 8 by catheter block 5; Pull bar 4 runs through catheter block 5 joints 6 back and thereafter and links to each other; There is brace 7 to be connected between joint 6 and the handle 8.When handle 8 opened, brace 7 was stretched, the reach of pulling joint 6, so pushing drawing rod 4 makes chuck 1 deviate from mutually with chuck 2 on the outer tube 3; When handle 8 was inwardly closed, brace 7 was pressed downward, and pulling joint 6 retreats, and therefore spurs pull bar 4 chuck 1 is compressed into to chuck 2, until closely being fastened, clamps suture needle therebetween.Therefore in the operation stitching process, fixed angle type needle holder of the present invention can be by the folding of two chucks up and down, ceaselessly be adjusted at the bite and the sensing of suture needle on the chuck occlusal surface, seek the best and hold the pin angle position, so that accurately successfully finish the suture operation on all places.
