Description

Disposable using-system suspender

Technical field

The utility model relates to a kind of surgical operating instrument, relates in particular to the suspension apparatus of organizing using in operation intervention procedure.

Background technology

In minimal invasive surgical procedures, surgical field of view is often subject to organ, muscle, the impact of the tissues such as cartilage. Conventional method is for example, to obtain better surgical field of view by the posture (Trendelenburgposition) of mobile sufferer change sufferer. This method is not convenient concerning doctor, also may cause larger wound to sufferer.

Therefore, in order to obtain better surgical field of view and increase the security of performing the operation in surgical procedure, much organize retracting of internal organs, separate, fixed apparatus is developed. Chinese patent literature CN201120103023 provides " three leaf fan-shaped forceps ", comprises a main body, and this main body is tong-like. This body head is two distraction forcep pages and the fixing pincers of a slice leaf, and there is a chute three pincers page bottoms. Overlapping and and the link pin of these three blade bottom end. Link pin is connected with flexible handle by pull bar, detains handle and just can allow a pincers pages fanning when use. Just can stir organ with fan-shaped forceps page afterwards, optimize visual area. This apparatus was to be human body direct-view operation designing originally, and in practice, promising Minimally Invasive Surgery uses institute to improve again. Really tissue can be pushed aside or organ exposes visual area with this apparatus, but still there are several important defects in this apparatus. In Minimally Invasive Surgery, in order to reduce patient's the pain of injury, Wicresoft's duct quantity should be more few better. And while using this apparatus, need to execute pincers by Wicresoft duct. If still need after moving tissue or organ to be fixed, need to allow this apparatus stay in human body, this will take a Wicresoft duct. And in this case, operation operates and fixes this apparatus by extra assistant of needs. Therefore, in Minimally Invasive Surgery, retract fixing human tissue with this apparatus and organ is not obviously optimal scheme. Chinese patent literature CN101933822A provides " for the tape channel three leaf fan-shaped forceps of surgery Minimally Invasive Surgery ", and it has changed linear claw beam, makes it become fold-line-shaped, and allows other apparatuses to pass through with a passage in the middle of claw beam. The claw beam of its fold-line-shaped enter behind abdominal cavity with claw beam on passage at an angle, the space of having created operation for the passage of access instruments. But this does not solve above-mentioned technological deficiency completely, still needs manpower to maintain the position of apparatus in operation. And its seal wire of controlling pincers page diastole and claw beam bending also can pass through same Wicresoft aperture, this will certainly reduce the pore size of its instrument channel. And these apparatuses are all that the material being used by non-once is made, it controls the body fluid and the tissue that in the hole of frame for movement of pincers page, are easy to residual sufferer, needs after surgery carefully to clean and sterilization.

Now, Minimally Invasive Surgery is advocated minimizing Wicresoft number of channels and is reduced the postoperative slight illness of patient, can reduce greatly the postoperative pain of injury of patient as one channel Minimally Invasive Surgery. Therefore, research can not take Wicresoft duct, can effectively retract again and apparatus that fixing human tissue or organ expose visual area is far reaching.

Summary of the invention

The problem of the required solution of the utility model is that a kind of disposable suspender of organizing will be provided, and in the situation that not taking Wicresoft duct, can effectively retract and fixing human tissue, does not need again to take doctor's both hands. This disposable suspender of organizing comprises an implanting needle, a suspender and a locking device.

Implanting needle main body is an intubate, and this intubate has the tail end (needle end) of an inclined-plane cutting. At the transparent plastic housing of near-end (nearly user's end) of this implanting needle. Suspender just enters implanting needle by this near-end outer cover, from tail end out. Under such structure, suspender can be temporarily fixed on implanting needle after entering implanting needle, and suspender can be continued to advance the then tail end of suspender to lean out and to enter human body from implanting needle tail end afterwards. When implanting needle pierces through or passes after destination organization, then the another side that suspender can be advanced tissue starts. The inclined-plane cutting of implanting needle tail end is used for penetrating that abdominal wall enters that then abdominal cavity pierces through and through destination organization. This implanting needle can be made up of the steel of medical grade.

Suspender is made up of a longitudinal main body, and main body has a tail end, and a near-end. Longitudinally main body is caudad extended by near-end, and the even thickness of main body is consistent until approach tail end, and this thickness is between 1mm-2mm. In the region that approaches tail end, the attenuation gradually of the thickness of material, the region of this thickness attenuation can form a shoulder type. The tail end of body is connecting a tail end bar by coupling part. The region that is connecting area of reduced thickness and tail end bar becomes coupling part, and this coupling part and main body are a free angle, and this angle can be 0-150 °, is preferably 30-120 °, is preferably 90 °. Tail end bar can be folded and arranged into implanting needle before using, and after puncture needle is through destination organization and organ, it presents " T " font in the situation that launching. In the time of reverse traction suspender, tail end bar can prop up destination organization, and it is pulled together. Wherein tail end bar can be made up of Part I and Part II two parts, the Part I that even forms tail end bar is continued to extend in coupling part, the Part II of tail end bar is extended to other direction by Part I, the thickness of Part I and the longitudinally consistency of thickness of main body, the thickness of Part II is the half of the thickness of longitudinal main body, the thickness of coupling part and the consistency of thickness of Part II.

The material of the elongation main body of suspender, coupling part, tail end bar is in full accord or internally inconsistent between two, its material can be selected from polypropylene material, PMA or polymethyl methacrylate, preferably form from high density poly propylene material is molded, the mechanical constraint that wherein causes tail end can present " T " font under deployed condition is to be propagated and caused by the crystal structure of its material.

The locking device that this device relates to is a transfusion pipe clamp, can be a transfusion pipe clamp, and it has elasticity and relies on frictional force to fix hanger. When suspender is drawn to destination organization or organ behind suitable position, can suspender be fixed with locking device. Patient just can operate other apparatus like this.

The utlity model has following advantage:

(1) the utlity model has disposablely, reuse without sterilization.

(2) the utility model, in use without taking Wicresoft duct, can not conflict with other apparatuses.

(3) retract and fixing organization or organ after, again lock after can unlocking at any time and adjust tissue or organ site if feel dissatisfied, adjust very convenient.

(4) using when this suspender without extra personnel, behind locking suspender position, patient goes in just can getting back to operation, maintains without manpower the position that tissue or organ retract.

Detailed description of the invention

As Fig. 1, suspender is made up of a longitudinal main body 1, and main body has a tail end 8, and a near-end 7. Longitudinally main body is caudad extended by near-end, and the even thickness of main body is consistent until approach tail end. In the region 2 that approaches tail end, the attenuation gradually of the thickness of material. The tail end of body is connecting a tail end bar by coupling part 3. Tail end bar 5 is made up of two parts, is called Part I 4 and Part II 6. The near-end 7 of main body is the curve with fixing curvature, is a region of holding for operator. The material thickness uniformity of main body 1, until the thickness of caudal part reduces region 2 and coupling part 3. Thickness reduces the Thickness Ratio body thickness of region and coupling part and will lack, and the thickness of comparative optimization should be the half of body thickness. Coupling part 3 is continued extension and is even formed tail end bar Part I 4. Tail end bar Part II 6 is extended by Part I. The diameter of suspender main body should be controlled within the specific limits, between 2.0mm, ensures that it is in having enough intensity at 1.0mm, is unlikely to again to cause the too large wound that enters. Its length should be controlled at 200mm between 350mm, can have enough length to enter human body, can some stay and externally grasp to patient again.

As Fig. 2, implanting needle main body is tubulose 9, and this part can be made up of the steel of surgical grade, and inner tubular portion aperture should allow suspender pass through. Tubular body should have certain length enough to pierce through abdominal wall to enter abdominal cavity penetration of target tissues or organ. Tubular body end is a needle point 11 that has cutting inclined-plane, can pierce through abdominal wall and human tissue organ. Implanting needle near-end is a transparent near-end outer cover 10, and this near-end outer cover surface can be transformed into rib shape, or makes lines and conveniently grasp. Suspender enters implanting needle by near-end cover.

The material of suspender main body is preferably made up of polymeric material, is preferably highdensity polypropylene material, has the toughness under rigidity and low temperature concurrently. Use such material, make the tail end bar of suspender can folding, can enter implanting needle (Fig. 3). In order to make the tail end bar can folding, with regard to its thickness, thickness reduces part 2 and the thickness of tail end bar Part II 6 and is preferably the half of the thickness of suspender main body. With regard in length, the length of tail end bar Part II 6 should be less than the length of thickness minimizing part 2.

The utility model provides one to be enclosed within and in endoscope micro-wound process, to use this suspender to retract and the scheme of fixing human tissue or organ simultaneously. In surgical procedure, when visual area is organized or the impact of organ, or operative region has overlapping tissue or organ, can use this suspender to retract. Before use, first suspender tail end to be loaded into implanting needle from implanting needle near-end cover. For the convenience of the users, in suspender main body, also have two position marks 12 and 13 (Fig. 1). These two position marks are on the measured position of prior survey. In the time that user packs suspender into implanting needle, advance suspender always, in the time finding that primary importance mark 12 aligns implanting needle near-end cover, illustrate that the tail end bar 5 of suspender has arrived the end 11 (Fig. 3) of implanting needle. Now suspender has loaded completely, can use. In use, thrust the position that implanting needle can be suitable from the stomach wall of having sterilized. When implanting needle thrusts abdominal cavity, can capture destination organization or organ with clamp, and with implanting needle penetration of target tissues or organ 14 (Fig. 4). Just can continue to advance afterwards suspender, until second place mark 13, now the tail end bar 5 of suspender has leant out implanting needle end and has launched, and forms " T " font. Now can extract implanting needle out abdominal cavity, suspender is stayed put. Become afterwards the position that suspender can be drawn from stomach wall come adjustment aim histoorgan. When target organ tissue arrives behind satisfied position, just can lock in vitro with locking device (as Infusion clip) position of suspender. Patient just can carry out the operation of other operations afterwards. When operation finishes or do not need to retract histoorgan, need to remove suspender time, first clamp the tail end bar Part I 4 of suspender with clamp, cut off afterwards thickness in suspender main body and reduce part 2, just main body can be extracted out from abdominal cavity. Tail end bar can take out from Wicresoft duct with clamp.
