Abstract

Disclosed is a puncture casing device, which is used to perforate operation appliances. A hollow pipe is adopted as the main body; the two ends of the pipe are respectively provided with a mouth; a filler box is arranged on the outer margin near one pipe mouth; a cap is arranged on the filler box; additionally, a capsular bag is arranged around the outer margin of the pipe; and the capsular bag is provided with a filling opening for the air or working fluid to be filled into. When the capsular bag is made to expand, the expanding effect makes the puncture casing be perforated into the proper position of the human body to be clung to the human body, thereby improving the stability of the puncture casing in the operation.

Description

The puncture casing device

Technical field

This utility model relates to a kind of casing bit, particularly a kind of puncture casing with fixed structure.

Background technology

In present medical domain, for safety and the convenience that improves operation, develop especially and a kind of puncture cover, after utilizing puncture casing to penetrate human body, again with operational tool, lead the way deeply to human body inside by puncture casing is formed as scalpel or endoscope etc., thereby be beneficial to the carrying out of operation.

And present employed puncture cover, earlier on human body, pre-determine puncture position by the medical personnel that undergo surgery, again puncture casing is penetrated this precalculated position, carry out this operation according to different operation purposes again, the inlet that needs simultaneously to continue to offer by this puncture casing in operation process injects or the extraction saline solution, thereby keeps the degree of getting a clear view of this operative site.

Yet employed puncture casing in the puncture operation process may be because the human body otch is too little be difficult to puncture tube is packed in the human body, if the human body otch excessive cause saline solution to leak and puncture tube slip or operative scar excessive; Therefore, traditional puncture casing structure afterwards is provided with thread surface especially in order to solve this inconvenient problem on the outer surface of puncture casing, wishes by this anti-skidding screw thread puncture tube to be screwed in the degree of fitting tightly of human body and increase and human body.

But, usually the caliber than puncture casing is also big in the site of puncture that produces owing to underwent operative on human body, therefore being arranged on skid resistant course on the outer surface of tube body can't directly touch human body and can't play a role, thereby can't solve existing problem smoothly, this has become the problem place that the present desire of those skilled in the art solves.

The utility model content

At above-mentioned defective, main purpose of the present utility model is to provide a kind of puncture casing device with cramped construction, by the capsule bag with extended function is set on the puncture casing edge surface, after making this puncture casing penetrate human body, make this capsule bag amass expanse according to different site of puncture sizes, be close to human body, thereby fix the position of this puncture casing.

In order to achieve the above object, this utility model mainly provides a kind of puncture casing device, and based on hollow tube, the two ends of this body have the mouth of pipe respectively, edge surface near an end mouth of pipe is provided with inlet, this inlet is provided with cap, in addition, on the edge surface of this body around the capsule bag is set, this capsule bag has hand-hole, be used to inject air or working fluid, make this capsule bag expanse, thereby make this capsule bag be close to the site of puncture of human body.

According to above-mentioned puncture casing device, make it penetrate human body after, make this capsule bag amass expanse according to different site of puncture sizes, be close to human body, thereby fix the position of this puncture casing.

The specific embodiment

Below content conjunction with figs. of the present utility model is illustrated:

Fig. 1 is a structure cutaway view of the present utility model.As shown in the figure, puncture casing device of the present utility model is based on hollow tube 1, body 1 is used to hold operational tool such as scalpel or endoscope, make it along with this puncture casing gos deep into human body, the two ends of body 1 have the mouth of

pipe

11 and 12 respectively, in addition, be provided with inlet 13 near body 1 edge surface of the top mouth of pipe 11, inlet 13 is provided with cap 14; In addition, on the edge surface of body 1, be surrounded with capsule bag 2, the outer surface of capsule bag 2 is a shiny surface in the present embodiment, and after capsule bag 2 is made molding, with capsule bag 2 surfaces around and the smooth edge surface that is fixed on body 1 on, form integrated structure with body 1, capsule bag 2 is provided with hand-hole 21, be used to inject air (as shown in Figure 2), or inject working fluid (as shown in Figure 3), be used to expand the volume of capsule bag 2 to capsule bag 2 inside.

Fig. 4 is an operation chart of the present utility model.As shown in Figure 4, this puncture casing device is used for the operation of human body, body 1 is penetrated the surface of human body 3 earlier, make an end mouth of pipe 12 of body 1 go deep into human body 3 inside, after body 1 is on the default position, inject fills with air capsule bag 2 by hand-hole 21, extend to human body 3 up to the volume of capsule bag 2 and to be close to, thereby body 1 is fixed on this default position of human body, and when scalpel 4 is penetrated by the mouth of pipe on the body 1 11, do not produce mobile so that when operation is carried out the fixing position of body 1.

Fig. 5 is the structure cutaway view of another embodiment of the present utility model.As shown in Figure 5, capsule bag 2 structures are one-body molded on the edge surface of body 1, the edge surface upper and lower end position of body 1 is respectively arranged with annular groove 15 in the present embodiment, and the bag two ends of capsule bag 2 are fixed in the groove 15, and annular groove 15 is corresponding to connect compacting ring 16, thus the fixing position of the bag of capsule bag 2, in addition, capsule bag 2 is provided with hand-hole 21, is used to inject air (as shown in Figure 6) or working fluid to capsule bag 2 inside, makes the volumetric expansion expansion of capsule bag 2; In addition, the outer surface of capsule bag 2 is graininess in the present embodiment, or on the outer surface of capsule bag 2 ring-like raised line or screw thread etc. is set, capsule bag 2 and human body 3 are close to after, play anti-skidding effect.

The above embodiment, it is preferred embodiment of the present utility model, but can not limit practical range of the present utility model with this, the equivalence of doing according to this utility model claim and description changes or modification, all should belong to patent covering scope of the present utility model.
