Abstract
The utility model discloses a special surgical instrument of endoscopic mucosa resection attached with a shield needle shaped incision knife. The special surgical instrument comprises a fixed handle and a movable handle, wherein a square groove hole is arranged on the fixed handle, and the movable handle moves forwards and backwards on the fixed handle in a position limiting way. The special surgical instrument is characterized in that the special surgical instrument also comprises a resection needle head, a traction steel wire and a duct, wherein the resection needle head is composed of a needle knife and a ball shield, the needle knife is inserted into the top of the ball shield and connected with a traction steel wire, and the bottom of the ball shield is connected with the duct; the two ends of the traction steel wire are respectively connected with the fixed handle and the resection needle head; and the duct is used for enwrapping the traction steel wire, and two ends of the duct are respectively connected with the fixed handle and the resection needle head. The mucosa is resected and simultaneously rinsed, thus the doctor more conveniently observes the surgery operation and the special surgical instrument also has the hemostasia function.
Description
Technical field
This utility model relates to the medical apparatus and instruments accessory, relates to a kind of and the matching used accessory of scope, relates more specifically to a kind of endoscopic mucosal with peltate pin type incision knife and peels off special-purpose operating theater instruments.
Background technology
When tumor that generates on people's the gastric mucosa or polyp, traditional mode is that treatment is operated in operation, adopts minimally-invasive treatment now; Do treatment through using scope; When using scope to do treatment, need supporting with it apparatus, in the gastroscope treatment; The apparatus that needs can cut the tumor that generates on the gastric mucosa or polyp and not damage coat of the stomach, peel off mucosa.In cutting treatment, ability flexible operation, use aspect; To this generic request; Each specialized factory is all among active development in the world, the scope that is used to treat that uses at present now down the operating theater instruments versatility is stronger, the special equipment of mucosa excision is not still had both at home and abroad.
The utility model content
The purpose of this utility model is, provides a kind of scope with gastric mucosa resection operation apparatus, solves above technical problem.
This utility model solves the technical scheme that its technical problem adopted:
A kind of endoscopic mucosal with peltate pin type incision knife is peeled off special-purpose operating theater instruments; Comprise fixed handle and flexible handle, said fixed handle is provided with the square groove hole, is used for spacing the moving in said flexible handle front and back on said fixed handle; It is characterized in that, also comprise:
One traction steel wire;
Said traction steel wire two ends connect said fixed handle and said excision needle section respectively;
One conduit;
The said traction steel wire of parcel in the said conduit, two ends are connected with said excision needle section with said fixed handle respectively;
One excision needle section;
Said excision needle section is made up of a pin cutter and a ball shield, and said pin cutter inserts from the top of said ball shield and is connected with said traction steel wire, and the bottom of said ball shield is connected with said conduit.
As the preferred version of embodiment, the diameter of said pin cutter is below 0.8mm;
As the preferred version of embodiment, this utility model also is provided with a hand-held hands handle;
Adopt the mode of being spirally connected to fix between said hand-held handle and the said fixed handle.
As the preferred version of embodiment, also be provided with high frequency input lock pin on the said flexible handle, and adopt between said high frequency input lock pin and the said traction steel wire and be electrically connected, can use the high-voltage electric shock excision to need diseased region after the energising.
As the preferred version of embodiment, said conduit outerwrap insulant, other the normal tissue cell of back injury inside of human body of avoiding switching on.
The beneficial effect of this utility model is: the pin cutter diameter that this product adopts is at 0.8mm; It mainly is to produce less wound at diseased region; And after cutting, can effectively stop blooding in custom-designed ball shield structure; Adopt this product operation simple and post-operative wound is little, easy infection not, the patient is rehabilitation rapidly.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the excision needle section sketch map of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing.This utility model is further specified.
When this utility model uses, be and the supporting use of scope.
As shown in Figure 1, Fig. 1 illustrates according to a kind of endoscopic mucosal with peltate pin type incision knife of first preferred embodiment of this utility model and peels off special-purpose operating theater instruments.
Especially; According to a kind of scope of first preferred embodiment of this utility model with peltate pin type incision knife; Comprise fixed handle 6 and flexible handle 5, fixed handle 6 is provided with the square groove hole, is used for spacing the moving in said flexible handle front and back on said fixed handle 6; This utility model also comprises 1 one at syringe needle of excision, traction steel wire 3, conduit 2; Excision needle section 1 is made up of pin cutter 11 and ball shield 12, and said pin cutter 11 inserts from the top of said ball shield 12 and is connected with said traction steel wire 3, and the bottom of said ball shield 12 is connected with said conduit 2;
The two ends of traction steel wire 3 are fixing with the pin cutter 11 of said fixed handle 6 and said excision needle section 1 respectively; Said traction steel wire 3 can drive said excision needle section 1 rotation; In operation, the tumor or the root of polyp that excise sometimes on needle section 1 and the gastric mucosa are in vertical direction, directly carry out resection operation; Damage coat of the stomach possibly; So must change the direction of excision needle section 1 through the rotation of traction steel wire 3, make tumor or the root of polyp on excision needle section and the gastric mucosa be in horizontal direction, thereby avoid damaging coat of the stomach;
The two ends of conduit 2 are fixing with the ball shield 12 of said fixed handle 6 and said excision needle section 1 respectively, the said traction steel wire 3 of parcel in the said conduit 2.
Flexible handle 5 is provided with high frequency input lock pin 51, and high frequency input lock pin 51 can conduct with traction steel wire 3 and be connected, and can use the high-voltage electric shock excision to need the position of excision after the energising.
Conduit 2 outerwrap insulant, other normal structures of back injury inside of human body of avoiding switching on.
More than show and described ultimate principle of this utility model and the advantage of principal character and this utility model.The technical staff of the industry should understand; This utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the description that this utility model just is described; Under the prerequisite that does not break away from this utility model spirit and scope, this utility model also has various changes and modifications, and these variations and improvement all fall in this utility model scope that requires protection.This utility model requires protection domain to be defined by appending claims and equivalent thereof.
