Abstract
The invention provides a purse-string device for a surgical department, comprising handle holders and chunk assemblies, wherein a holding part is arranged at the tail of each handle holder; each chunk assembly comprises a casing and a nail bin assembly arranged inside the casing; the nail bin assembly comprises a nail bin, a nail pushing piece and a nail, wherein the nail pushing piece and the nail are arranged in the nail bin; the handle holders and the chunk assemblies can be slidably connected together; and a positioning mechanism is connected between two chunk assemblies. The invention has the benefits that: since the handle holders and the chunk assemblies can be slidably connected, the purse-string device for the surgical department can be used for operations at special positions such as high-position operations of esophagus so as to widen the service range of the devices.
Description
Technical field
The present invention relates to a kind of purse-string suture device, especially a kind of automatic purse stitching instrument used for surgery belongs to medical instruments field.
Background technology
Purse-string device for surgical department is a kind of medical apparatus and instruments that often uses when physiological tissues such as intestinal are carried out surgical operation, and the quality of this instrument performance directly influences the operation process, plays important effect for surgical effect.In the prior art, all to do purse string suture when using Binding Instrument to carry out suture operation, so that firmly ligation after inserting center-pole could be implemented the bookbinding operation then at the organ stump.The method of implementing the purse string suture operation has two kinds: a kind of is manual suture, and not only operation is very wasted time and energy, and inserting needle has and have shallowly deeply, and needle gage is also inconsistent; Another kind is to use the purse string suture pincers, passes the jaw that accompanies tissue together with the pin band wire and carries out purse string suture, and shortcoming is to pass an aperture of jaw, inconvenient operation with pin.
The automatic purse-string suture device that arises at the historic moment, the problems referred to above have been solved largely, Chinese patent ZL200510123051.4 has put down in writing a kind of automatic purse-string suture device, it is made up of handle holder and nail bin groupware, two handle holders intersect forms shears shape structure, and nail, pushing slice of nail and purse wire are arranged in the nail bin groupware.After clamping up and down two handle holders, the nail in the nail bin is just come out by percussion, purse wire is fixed on organizes outer wall, just can tighten up purse wire bundle pocket then.Can see that the process of making pocket is very simple, save time, but because be to be rigidly connected between the handle holder of this purse-string suture device and the nail bin groupware, use dumbly that can not adapt to the operation of some specific positions, for example esophagus is high-order performs the operation.
The present invention quotes the content that this patent is put down in writing as prior art.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of automatic purse stitching instrument used for surgery that can regulate handle holder and chuck component position as required is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of purse-string device for surgical department, comprise: two handle holders that are hinged and be arranged on the forward chuck component of handle holder, the afterbody of described handle holder is the grip part, described chuck component comprises housing, and be arranged on the nail bin groupware of enclosure interior, described nail bin groupware comprises nail bin and places nail bin interior pushing slice of nail and nail that described handle holder and chuck component link together slidably, and are connected with a detent mechanism between two chuck components.
Further, described handle holder is provided with chute, and the housing of described chuck component is provided with the guide plate that can slide in chute.Perhaps, the housing of described chuck component is provided with chute, and described handle holder is provided with the guide plate that can slide in chute.
Again further, described chute is a dovetail groove.Perhaps the cross section of described chute is a T-shape.
Further, described detent mechanism is the gag lever post that is connected between the housing of two chuck components.
Beneficial effect of the present invention is mainly reflected in: because handle holder and chuck component are for being connected slidably, so automatic purse stitching instrument used for surgery of the present invention can adapt to some for example operations of the high-order such specific position of performing the operation of esophagus, enlarged the scope of application of apparatus.In addition, no matter be before art or in the art, the doctor can regulate according to the demand in the visual field, has increased the adaptability of apparatus to practical application, has made things convenient for doctor's use.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: the front view of purse-string device for surgical department of the present invention.
Fig. 2: the vertical view of purse-string device for surgical department of the present invention.
Wherein:
1 handle holder, 2 grip parts, 3 chuck components
4 housings, 5 nail bins, 6 chutes
7 gag lever posts, 8 bumper bars, 9 guide plates
The specific embodiment
The present invention has disclosed a kind of automatic purse stitching instrument used for surgery, in conjunction with illustrated in figures 1 and 2, the same with prior art, comprise two handle holders 1 that similar shears is equally hinged, the afterbody of handle holder 1 is to be provided with bumper bar 8 between 2, two the handle holders 1 in grip part.The front end of handle holder 1 is a chuck component 3, and described chuck component 3 comprises housing 4, and is arranged on the nail bin groupware of housing 4 inside, and described nail bin groupware comprises nail bin 5 and places pushing slice of nail and nail in the nail bin 5.Difference with the prior art is: described handle holder 1 and chuck component 3 link together slidably.In the present invention, described handle holder 1 is provided with chute 6, and the housing 4 of described chuck component 3 is provided with the guide plate 9 that can slide in chute 6.Certainly, on the housing 4 of chuck component 3, establish chute 6, establish guide plate 9 on the handle holder 1, belong to the equivalent transformation scheme of present embodiment, still in protection scope of the present invention.Again further, described chute 6 is a dovetail groove, and perhaps its cross section is a T-shape, guarantees that guide plate 9 is difficult for deviating from from chute 6.
Owing to after chuck component 3 has slided, also need purse string suture, so between two chuck components 3, be connected with a detent mechanism 7.Described detent mechanism is the gag lever post 7 that is connected between the housing 4 of two chuck components 3.This gag lever post 7 is inflexible, slides into identical position so can retrain two chuck components 3, plays a positioning action.In addition, in this preferred embodiment, be interference fit between chute 6 and the guide plate 9, guarantee that handle holder 1 is relative immobilized with chuck component 3 under the situation that is not subjected to external force.
During use, two handle holders 1 are opened, regulated the position between chuck component 3 and the handle holder 1, be about to chuck component 3 and get final product, make chuck component 3 be " L " type or T-shape with respect to handle holder 1 with respect to 1 slip of handle holder.Between nail bin 5, place tissue then, closed then two handle holders 1, firmly extruding, nail is just come out by percussion, between puncturing the top layer of tissue and purse wire being wrapped in nail and organize.Open handle holder 1 at last, removal equipment tightens up purse wire, finishes the pocket seam and pricks.
The present invention still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
