Description

Intracerebral hematoma Wicresoft drainage device

Technical field

This utility model belongs to medical instruments field, is a kind of intracerebral hematoma Wicresoft drainage device.

Background technology

The process of tradition brain subdural hematoma operative treatment is: at first with incision of scalp, the reuse drill bit is a sphenotresia, inserts drainage tube down to the brain endosclerite, thereby the hematocele that makes the formation hematoma brain endosclerite under is outside drainage tube is drawn cranium.Because the process need incision of scalp of this operative treatment, particularly the head end of drainage tube inserts in the brain under without any constraint, and it is long to exist operation technique complexity, time, easy damaged brain table and cerebral tissue, be difficult to guarantee therapeutic effect, the high deficiency of surgery cost.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of simple in structure, and operation technique is easy, the time is short, can reduce brain table and brain tissue impairment, easily guarantees therapeutic effect, easily applies the intracerebral hematoma Wicresoft drainage device that surgery cost is low.

Solving the technical scheme that its technical problem adopts is: a kind of intracerebral hematoma Wicresoft drainage device, it comprises drill bit, drainage tube, its special character is: have the skull drilling tool, the structure of described skull drilling tool is, go into drill bit in the outer tube interpolation, on the drilling rod of drill bit on fixed drillstock, the outer tube fixed pipe handle all be connected with dead ring; Have the guiding drainage device, the structure of described guiding drainage device is, goes into the trocar in the outer tube interpolation, inserts drainage tube in the trocar.The trocar head end of described insertion outer tube is provided with bent angle.

Intracerebral hematoma of the present utility model Wicresoft drainage device need not be operated on, and directly adopts and inserts skull drilling tool that drill bit forms in the outer tube to sphenotresia, outer tube is placed on the skull, and drill bit is extracted from outer tube; Go into the trocar toward the outer tube interpolation again, in the trocar, insert the guiding drainage device that drainage tube is formed, the guiding drainage device trocar head end bent angle guiding and the constraint under, drainage tube enters the drain position of brain table the best by the bending of guiding direction and directly contacts with the brain subdural hematoma, guarantees drain and falls cranium pressure speed.Acute cerebral hernia also there is first aid effect.Have simple in structure, advantage such as operation technique is easy, the time is short, can reduce brain table and brain tissue impairment, easily guarantees therapeutic effect, easily applies, and surgery cost is low.

Fig. 2 is an A-A cross-sectional schematic among Fig. 1.

Fig. 3 is the guiding drainage device structure cross-sectional schematic of intracerebral hematoma Wicresoft drainage device.

Among the figure: 1 drainage tube, 2 trocars, 3 needle handles, 4 pipe handles, 5 outer tubes, 6 drill bits, 7 drillstocks, 8 dead rings.

The specific embodiment

The utility model is described in further detail to utilize embodiment shown in the drawings below.

With reference to Fig. 1-2, intracerebral hematoma Wicresoft drainage device has the cranial drill tool, and the structure of described skull drilling tool is, inserts drill bit 6 in outer tube 5, on the drilling rod of drill bit 6 on fixed drillstock 7, the outer tube 5 fixed pipe handle 4 all be connected with dead ring 8 employing emboss pits.

With reference to Fig. 3, intracerebral hematoma Wicresoft drainage device has the guiding drainage device, and the structure of described guiding drainage device is to insert the trocar 2 in outer tube 5, insertion drainage tube 1 in the trocar 2.The trocar 2 head ends of described insertion outer tube 5 are provided with bent angle, are fixed with needle handle 3 at another head end of the trocar 2.The trocar 2, outer tube 5 and drill bit 6 are all made of stainless steel material.Drainage tube 1 is a silica gel tube.

Use the operating procedure of intracerebral hematoma Wicresoft drainage device: for the patient of brain subdural hemorrhage, the accurate point of inserting needle, the degree of depth, aspect and labelling are determined in the CT examination location in advance.The patient enters the minor operation chamber, under sterilization local anesthesia, the bar portion of the drill bit 6 of skull drilling tool is loaded on the chuck of electric drill and makes the outer tube 5 of skull drilling tool and the front portion of drill bit 6 pierce intracranial, then, extracts drill bit 6.Again the trocar 2 is inserted in the outer tube 5, drainage tube 1 is inserted in the trocar 2, under the guiding and constraint of the trocar 2 head end bent angles, drainage tube 1 enters the drain position of brain table the best by the bending of guiding direction and directly contacts with the brain subdural hematoma, and hematocele is drawn outside the cranium, after operation finishes, according to patient's intracranial hematocele amount, determine to stay the pipe time, a check CT sees that hematocele is clean, then extract the guiding drainage device, finish whole therapeutic process.
