Embodiment

To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings The utility model is further described example.

Embodiment one

Refering to Fig. 1, the utility model provides a kind of sieve sinus and punctures hole making drill, including sleeve 2, the rear end connection of sleeve pipe 2 There are handle 1, in addition to an inner core 3, inner core 3 is stretched out through described sleeve pipe 2 and from the front end of sleeve pipe 2, and the front end of inner core 3 is provided with The puncturing head 4 of the taper of perforate is punctured to sinus tissue.Need to cut off most of sieve room in existing sinus Balloon dilation Scleroseptum and mucous membrane, postoperative wound easily cause oedema, growth scar, and scar tissue can again be formed at nasal sinus mouth and protruded and shadow The drainage of snort sinus, such operation method wound are bigger.The utility model carries the puncturing head 4 of taper, sharp puncture First 4 can pierce out micropore on sinus tissue is drained, and without cutting off most of sieve room scleroseptum and mucous membrane, reduces operation wound Wound, truly reach the purpose of Minimally Invasive Surgery.

After puncturing head 4, which pierces through sinus tissue, outputs micropore, if desired further expand the hole outputed, then need to puncture First 4 continue on forward to expand micropore, further go deep into if directly holding handle 1 and will sieve sinus puncture hole making drill in nasal sinus, Then sleeve pipe 2 easily scratches to the tissue in nasal sinus, causes unnecessary damage, and therefore, refering to Fig. 3 and Fig. 4, sieve sinus punctures perforate Device also includes push rod 5, and the handle 1 is articulated with described one end of push rod 5, and the push rod 5 and the inner core 3 connect, and handle 1 rotates Inner core 3 is controlled to move horizontally flexible, the bottom of puncturing head 4 is provided with the first recess 42, and described sleeve pipe 2 is close to the puncturing head 4 One end is provided with the second recess 21, and the cavity for accommodating sieve sinus tissue is formed between the recess 21 of the first recess 42 and second. Handle 1 is opened, inner core 3 is pushed forward（Refering to shown in Fig. 2 and Fig. 4）, puncturing head 4 continued on forward to expand micropore, is collapsed Handle 1, inner core 3, which is pulled, rearward to be moved, and the sharp edge of the first recess 42 cuts away pathological tissues in sieve sinus when retracting, The cavity formed between first recess 42 and the second recess 21 accommodates the sieve sinus tissue being cut, so, without such as sinus sacculus Ductal ectasia art cuts off most of sieve room scleroseptum and mucous membrane like that, by collapsing handle 1 the first recess 42 can be made to play cutting disease Become the effect of tissue, it is simple for structure, it is easy to operate.

Refering to Fig. 5, inner core 3 is wholely set with puncturing head 4.

Embodiment two

Puncturing head 4 is easily passivated influence using its tip after a period of time and punctures effect, at this moment can dismantle puncturing head 4 The puncturing head 4 more renewed after getting off, if but inner core 3 and puncturing head 4 be wholely set, certain difficulty can be caused to replacement operation, In order to facilitate regular maintenance and replacing, refering to Fig. 6, in the present embodiment, a protuberance 30, puncturing head 4 are fixedly connected with inner core 3 Bottom center be provided with hole portion 40, be interference fitted in the insertion hole portions 40 of protuberance 30 and with hole portion 40.So, puncturing head is changed Extraction puncturing head 4 is only needed to allow protuberance 30 to depart from hole portion 40 when 4, operation very simple is convenient, while protuberance 30 and hole portion 40 interference fit ensure that bonding strength sufficiently large between inner core 3 and puncturing head 4, prevent that puncturing head 4 departs from perforation Inner core 3.

Embodiment three

Refering to Fig. 7, in the present embodiment, a protuberance 30, the bottom center of the puncturing head 4 are fixedly connected with inner core 3 Hole portion 40 is provided with, the outer surface of protuberance 30 is provided with external screw thread, and hole portion 40 is provided with internal thread, protuberance 30 and hole portion 40 are connected through a screw thread.Puncturing head 4 is rotated when changing puncturing head 4 puncturing head 4 can be separated with inner core 3, is connected firmly, is dismantled It is time saving and energy saving.

Example IV

Further, refering to Fig. 8, in the present embodiment, the outer surface of the puncturing head 4 of taper is provided with along the axle of puncturing head 4 To the helicla flute 41 of extension, puncturing head 4 can leave sieve sinus tissue bits in nasal sinus after perforating, if these sieve sinus tissue bits are not in time Discharge can then hinder the ventilation of nasal sinus to drain, and aggravate the symptom of sinusitis in patients, and helicla flute 41 can accommodate sieve sinus tissue bits, perforation Puncturing head 4 is retracted from nasal sinus afterwards drains sieve sinus tissue bits, improves the effect of ventilation drainage in nasal sinus.

The utility model punctures hole making drill by providing a kind of sieve sinus, new with telescopic taper puncturing head, this practicality Type punctures hole making drill by providing a kind of sieve sinus, with telescopic taper puncturing head, the utility model can be used directly right The drainage of sinus tissue perforation is sieved, to coordinate nasal sinus Balloon dilation, reaches excellent Minimally Invasive Surgery effect, avoids conventional screen sinus The big surface of a wound caused by open art and postoperative easily there is phenomena such as oedema, scar.

It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model The protection domain that profit requires.
