Be used for abdominal operation and place the biopsy needle guide of drainage tubeTechnical field
This utility model relates to and is used for the transfering human medium or for take out the medical tubular instrument field of medium in human body, is specially a kind of biopsy needle guide that drainage tube is placed in abdominal operation that is used for.
Background technology
Need the conventional various drainage tubes of placing behind the abdominal surgery, as single lumen catheter, two sleeve pipe, T type pipe, or the like.When drawing in the drain process abdominal incision, Chang Rongyi causes draining hole place wound healing bad, even infection of incisional wound, therefore need draw drain at other other puncture of stomach wall of otch.Owing to there is not special equipment, traditional stomach wall puncture mode is with behind the sharp knife open abdomen skin, protrude into the abdominal cavity from outward with the medium size mosquito forceps, simultaneously with tissue forceps tractive otch free edge to form interaction force, make the medium size mosquito forceps can pass subcutaneous tissue, muscular tissue and peritoneum and enter the abdominal cavity, strut repeatedly to enlarge puncturing hole with mosquito forceps then, live drainage tube with the mosquito forceps clamp at last and pull out puncture.There is following shortcoming in traditional stomach wall puncture mode: 1. medium size mosquito forceps head circle is blunt, and the strength of passing stomach wall is mainly from relative tractive, so traditional stomach wall puncture mode is passivity violence puncture, may cause damage to local abdominal wall tissue, such as conduction hole more serious situations such as ecchymosis on every side occurring; 2. in advance with the sharp knife open abdomen, cut choice of location and may have deviation, select to exist the puncture of deviation to pass drainage tube, may cause drainage tube in situations such as intraperitoneal overbendings, it is unobstructed to influence drain; 3. the drain kind is various, and bore differs, may be excessive or too small with sharp knife at the otch of celiotomy incision, and medium size mosquito forceps expanded support in stomach wall is formed also to be not easy control via bore, thereby may bring unnecessary damage to the patient.Therefore, there is bigger limitation in traditional stomach wall puncture mode, needs a kind of special operating theater instruments to solve this problem.
The utility model content
In order to overcome the defective of prior art, a kind of drainage equipment that the skin damage is light in stomach wall puncture process, cutting accuracy is high is provided, the utility model discloses a kind of biopsy needle guide that drainage tube is placed in abdominal operation that is used for.
This utility model reaches goal of the invention by following technical solution:
A kind ofly be used for the biopsy needle guide that drainage tube is placed in abdominal operation, comprise the puncture needle needle body, it is characterized in that: the head of puncture needle needle body is an arc, and the both sides of puncture needle needle body head have the drain groove, and antiskid groove is carved with at the middle part of puncture needle needle body.
The described biopsy needle guide that is used for abdominal operation placement drainage tube, it is characterized in that: its central angle of arc of puncture needle needle body head is 60 °, antiskid groove be shaped as helix or by oblique line with the end to end zigzag that constitutes, the degree of depth of puncture needle needle body head drain groove and middle part antiskid groove all is 1/10~1/4 of a puncture needle needle body thickness.
The described biopsy needle guide that is used for abdominal operation placement drainage tube, it is characterized in that: the afterbody of puncture needle needle body is the anticreep link, the anticreep link is the pagoda shape termination that is formed by 3~8 round platforms stacks.
The described biopsy needle guide that is used for abdominal operation placement drainage tube, it is characterized in that: the diameter of puncture needle needle body is any one among 5mm, 7mm and the 10mm, the length of puncture needle needle body is 170mm.
This utility model is made with rustless steel, when using this utility model puncture, select corresponding puncture needle needle body according to the drainage tube diameter earlier, the afterbody of puncture needle needle body is inserted outer end, drainage tube abdominal cavity, the anticreep link of puncture needle needle body afterbody can play the fixation of slip-off preventing, the antiskid groove at puncture needle needle body middle part is the holding area, after placing drainage tube abdominal end position, select appropriate position, grip the puncture needle needle body and after intraperitoneal passes stomach wall, take off puncture needle, drainage tube is laid and is put in place, and other connects drainage bag.
The beneficial effects of the utility model are:
1. the tip of puncture needle needle body is the sharp sword of duckbill, can guarantee to be in the piercing process separation of sharp property, if select parallel angle puncture with the traveling of abdominal wall muscle fiber, then can at utmost reduce the damage of puncture to stomach wall; The otch size of the sharp keen sword open abdomen of duckbill skin just in time is the size of needle body diameter.
2. select drainage tube in Intraabdominal position earlier, select best puncture position according to the traveling of drainage tube then, thereby guaranteed that drain is unobstructed effectively.
3. there is multiple model available, really realized puncture as required.

The specific embodiment
Below further specify this utility model by specific embodiment.
Embodiment 1
A kind of biopsy needle guide that is used for abdominal operation placement drainage tube, comprise punctureneedle needle body 1, as depicted in figs. 1 and 2, concrete structure is: the head of punctureneedle needle body 1 is an arc, described arcual central angle is 60 °, the both sides of punctureneedle needle body 1 head have the drain groove,antiskid groove 11 is carved with at the middle part of punctureneedle needle body 1, the shape ofantiskid groove 11 can be helix or by oblique line with the end to end zigzag that constitutes, with the end to end zigzag that constitutes, the shape ofantiskid groove 11 as shown in Figure 3 by oblique line in the present embodiment employing.The degree of depth of punctureneedle needle body 1 head drain groove and middle partantiskid groove 11 all is 1/10~1/4 of punctureneedle needle body 1 thickness, and present embodiment gets 1/10.For the ease of fixing drainage tube, as shown in Figure 4, the afterbody of punctureneedle needle body 1 is an anticreep link 12, anticreep link 12 is the pagoda shape terminations that formed by 5 round platform stacks, according to actual needs, described round platform number can be between 3~8, and round platform number anticreep effect more at most is good more.
Punctureneedle needle body 1 minute A, B and three kinds of models of C, its specification and purposes as shown in Table 1, the length of punctureneedle needle body 1 is 170mm.
Table one
| Model | Puncture needle needle body diameter (mm) | Purposes |
| A | 5 | No. 18 T pipes, catheter |
| B | 7 | 20~No. 24 T pipes, thin single lumen catheter |
| C | 10 | Thick single lumen catheter and two sleeve pipe |
Present embodiment is made with rustless steel, when using the present embodiment puncture, select corresponding punctureneedle needle body 1 according to the drainage tube diameter earlier, as shown in Figure 5 and Figure 6, the anticreep link 12 of punctureneedle needle body 1 afterbody is inserted the outer end, abdominal cavity ofdrainage tubes 2, anticreep link 12 can play the fixation of slip-off preventing, theantiskid groove 11 at punctureneedle needle body 1 middle part is the holding area, after placing the abdominal end position ofdrainage tube 2, select appropriate position, grip punctureneedle needle body 1 and take off puncture needle after intraperitoneal passes stomach wall,drainage tube 2 is laid and is put in place, and other connects drainage bag.
